In this section you will find online tests that will help you prepare for passing the OGE (GIA) in biology. We wish you success!

The standard OGE test (GIA-9) of the 2019 format in biology contains two parts. The first consists of 28 tasks with a short answer, the second - of 4 tasks with a detailed answer. In this regard, only the first part (i.e., the first 28 tasks) is presented in this test. According to the current structure of the exam, only 22 of these questions offer answers. But for the convenience of passing the tests, the site administration decided to offer answers in all tasks. However, for tasks in which answer options are not provided by the compilers of real control and measuring materials (KIMs), the number of answer options has been significantly increased in order to bring our test as close as possible to what you will encounter at the end of the school year.

When completing tasks A1-A24, select only one correct option.

Training options for the exam in biology

After the thematic tasks in biology, start practicing. Since in order to demonstrate a high level of knowledge, it is necessary to confidently work with diagrams, tables and graphs. Explain biological processes using graphical information.

First of all, download FIPI, which is a sample and gives an idea of the structure and form of complexity of future assignments for the exam.

Based on the new demo developed 10 training options, register and track the level of knowledge in your personal account.

Identify, analyze mistakes and train again. Your success is the constant decision of options during preparation!

The USE test in biology 2019 includes 28 tasks.

Part 1 contains 21 tasks with a short answer (a sequence of numbers, a number, a word or a phrase)
Part 2 It contains 7 jobs with detailed answers (to give a complete answer explanation, description or justification, argue and express own opinion).

The variant is thematically grouped.

The first part contains 21 tasks, which are grouped according to the content blocks presented in:
- For multiple choice;
- To establish correspondence;
- To establish the sequence of processes or phenomena;
- Tasks in cytology and genetics;
- To complement the drawings;
- Analysis of a schema or table.
The second part contains 7 tasks. For the successful solution of which the student is required to own conceptual apparatus thoroughly and competently handle biological terms.

A short analysis of the conditions of some tasks

Tasks from the block of the first ticket:

- a biological fragment is presented, requiring the establishment of links between concepts;
- count the number of chromosomes and establish the number of cells formed during various processes;
- find examples in the text that correspond to the concepts;
- to test knowledge of species properties - select criteria from the test that correspond to the species.

Assessment of tests in biology USE

Per first part ticket maximum - 38 points.
For problem solving second part - 20 points.

The points received for correctly completed tasks are summed up.

Converting points to grades

0-35 points - 2,
36-54 points - 3,
55-71 points - 4,
72 and above points - 5;

To enter a budget place in a prestigious university, you need to score more than 84 points.

Decide! Dare! Strive for the best!

The final and entrance exams of 2018 are over. How much energy and eleventh kilograms given in the competition for admission to the budget places in the selected college. Everything has passed...

In this article, I appeal to you, the future applicants of 2019 and your biology teachers. The project is already out Demos 2019 from which it is clear that there will be no changes in the compilation of KIMs in 2019, which is very encouraging.

For a more focused, productive, high-quality exam preparation in 2019 is necessary to know the bottlenecks knowledge gaps identified in the preparation for passing examinations entrants in 2018.

Such an analysis of the results of passing exams in biology in 2018 is given

As in the past year, these authors have made such a detailed analysis that studying it in its entirety can take several hours from the most conscientious teachers and tutors. And it is unlikely that any of the future applicants will fully study this voluminous work of the authors.

To simplify the perception of vision paintings exam results in biology entrants in 2018,

in this my article, there is no information about the exam questions with which most students are handled and discussed those tasks which could only manage a few.

Examination work included questions largely similar to those of the 7-content blocks represented in.

Each variant examination work contained 28 tasks and consists of 2 parts.

Part 1 contained the 21 job, including:

7 jobs with multiple choice (with or without pattern);
6 - to establish the correspondence (with or without pattern);
3 - to establish the sequence of systematic taxa of biological objects, processes, phenomena;
2 - to solve biological problems of Cytology and Genetics;
1 - the complement of the missing information in the circuit;
1 - the complement of the missing information in the table;
1 - on the analysis of the information presented in graphical or tabular form.

Part 2 consisted of seven jobs from the detailed answer:

1 task into two response element 6 and jobs at three or more elements.

Exam results showed that job with detailed answer well differentiated exam participants according to their level of training.

Changes in the structure of the CMM in 2018 did not happen. However, compared with the previous year occurred changing the amount of the base figure (10 to 12 tasks) increased (from 12 to 9 jobs) and high (6 to 7 jobs) difficulty levels. Moreover, in the part 2 there CMM task with new scenes in lines 22, 23, 28.

In 2018 in the exam more than 133 thousand. People took part in biology. Exam in biology traditionally in demand and one of the five most popular choice for the finals.

In 2018, the average test score was 51.4 in biology. Marked by a strong tendency to reduce the number of participants with results in the range of 81-100 points.

This reduction can be attributed to the proportion of vysokoballnikov set of measures to enhance the expert committees subject areas, as well as the inclusion of part 2 KIM new subjects, demanding a clear argument, not play public or private knowledge on the subject. This allowed for better differentiation of the participants with the highest test scores.

Completed all the assignments and examination paper scored 100 points 48 graduates.

Analysis of the answers of the examinees, carried out in the Methodological Recommendations for Teachers by Rokhlov V.S. with co-authors made it possible to determine the range of problems, difficulties and typical mistakes of examinees in the development of a biology course.

Block 1. Biology as a science. Methods of scientific knowledge.

In this block, as well as last year, many mistakes were made on questions. concerning the methods of scientific knowledge.

For example, for the task of using the “tagged atoms” method to study the process of photosynthesis, 15% of the examinees received the maximum 2 points, and 78% received 0 points!

Quest, which was required to explain the use of centrifugation method to separate organelles of cells, 2 points received only 7% of examinees and 67% - got 0 points.

Block 2. Cell as a biological system.

In part 1 in line 3, some tasks showed very low results, although the tasks are “ridiculously” simple, not requiring any in-depth knowledge of biology.

For example, participants found it difficult to determine : the number of chromosomes in the somatic cell of the organism according to the chromosome set of the germ cell; the number of autosomes in the germ cell; the number of X chromosomes in a male reproductive cell.

Very low results were also obtained for the task where it was required to determine the properties of the genetic code. And that there may be a surprise, even if the authors of textbooks, "confused", identified the concept of "genetic information" and "genetic code." Therefore, I earnestly ask school teachers and biology tutors to pay close attention to such a misunderstanding.

Problem for most of the subjects were assignments, tests knowledge of the chemical composition of cells and the role of the chemical elements in the processes of life. An example of such a matching task.
CHARACTERISTICS
A) participates in the conduction of nerve impulses (2)
B) is part of the bone tissue (1)
C) is part of the lipid layer (1)
D) is part of nucleic acids (1)
D) participates in the transport of oxygen (3)
CHEMICAL ELEMENTS
1) phosphorus
2) potassium
3) iron ( The examinees put both iron and potassium into the bilipid layer of the membrane, forgetting that the membranes consist of phospholipids).

Tasks for comparing the characteristics of mitosis and meiosis and for comparing the characteristics of eukaryotes and prokaryotes turned out to be problematic.

Low internalized knowledge characteristics appeared dark phase of photosynthesis. Exam participants found it difficult to establish a correspondence between the structure of the chloroplast, shown in the illustration and place the flow of photosynthesis phases. And a quest to establish the sequence of processes, the lowest results were obtained for the job, which was necessary to determine the sequence of processes that occur during photosynthesis.

Complex were "task and matching 'when establishing the relationship between structure and function of cell organelles, metabolism processes, the type of cell division.

For reference line 7, with the task of Cytology to determine the number of chromosomes and DNA molecules in the different phases of mitosis and meiosis, chromosomes gametophyte and sporophyte plant cells,
maximum 3 points as last year received less than 5% of the participants. (Again, it must be noted that it is strange that so few students answer these questions correctly. These tests are almost no changes occur in KIMah and placed in the actual situation review FIPI over the past four years).

Here is an example of the job again, little right answers were given on that. "Chromosome set wheat somatic cells is 28. Determine the set of chromosomal DNA and the number of molecules in the cell during the formation makrospory ovule at the end of meiosis I and meiosis II. Explain the results in each case. " (This is a test task in this form was KIMah exam back in 2014, and repeated in the past year).

In line 23, suggested a drawing to determine the type and phase of cell division and argue your choice. With this task cope and to determine the phase and the type of cell division, led basis and get the maximum 3 points, only 3% of the participants.

The lowest results of the 24 lines were on the job to which it was necessary to analyze information on the genetic code, a prokaryotic cell, a plant cell, the cell nucleus, and errors in the text.

Line 27 is traditionally devoted to the testing of skills to apply knowledge in new situations to solve problems of cytology to determine the number of chromosomes and DNA molecules in different phases of mitosis and meiosis, chromosomes of cells of the gametophyte and sporophyte plant, the amino acid sequence in a protein molecule, using the genetic code table. Cope with such tasks for maximum 3 points only 11% of participants.

Here is an example of the job for which the results obtained below the average. A fragment of the DNA molecule has the nucleotide sequence: -A T A T A G A T C T C T T T T. Define the sequence of amino acids in a fragment of the polypeptide chain and justify your answer. What changes have occurred as a result of gene mutation in a fragment of the DNA molecule, if the fourth amino acid in the polypeptide has been replaced by an amino acid Glu? What is the genetic code of the property determines the possibility of the existence of different fragments of mutated DNA molecules? Justify the answer. To perform the job, use the table of the genetic code.

1) must first set the sequence of nucleotide triplets mRNA. Transcribed from that portion of the DNA fragment portion mRNA fragment is: UAU-UTSTS-UCA-GGA-AAA.
2) amino acid sequence: Tyr-Ser-Tyr-Gly-Lys.
3) To a fragment of the protein instead of the amino acid glycine was the amino acid glutamine, fourth triplet mRNA must be GAA or GAG. Accordingly, it will be mutant DNA triplet TTC in place of original or TSTTS TSTST.
4) Different triplets can code for the same amino acid - this is due to redundancy (degeneracy - "dumb" term) of the genetic code.

Thus, in general, on the unit 2 to the number of participants is weakly generated knowledge and skills may include :
1) knowledge of the chemical composition of cells;
2) knowledge of metabolic processes (e.g., photosynthesis);
3) the characteristics of the phases of mitosis and meiosis;
4) ability to determine the number of chromosomes and DNA molecules in cells in different phases of mitosis and meiosis;
5) establish the correspondence between the characteristics and specific metabolic processes;
6) determine the pattern of cell division of phases;
7) to justify and explain their choices.

Block 3. The organism as the biological system

Analysis of the results showed that most of the participants have mastered the knowledge about the body as a biological system, demonstrated the ability to solve the genetic problem. Equally successful implementation contributed to the fact that most of the models included in the task options, and USE. Nevertheless identified a number of problems in the knowledge and skills and on the subject.

In Part 1 fl th block, complex tasks were to determine the ratio of the number of phenotypes in the cleavage at the self-pollinated plants, with test cross digomozigoty or digeterozigoty.

In line 7 on multiple choice tests knowledge of terms and the basic laws of inheritance and variability, bases breeding and biotechnology. Here, most of the examinees have difficulty in selecting the provisions of the chromosome theory of heredity and characteristics of chromosomal mutations.

The quest line 8 on the correspondence to the number to be poorly assimilated knowledge to carry on embryogenesis (incorrectly detected signs of gastrulation).

In line 21 the special difficulties caused a task which required to explain the effect of mutations on accumulation of adipose tissue.

In Part 2 of this block in contrast to previous years, each text has a specific name that helps participants to choose the right test error correction in the text. Here is an example of the task, the results of which were low.
Find three errors in the above text "Mutations." Indicate the numbers of sentences in which errors were made, correct them. Give the right wording.
(1) Mutation - a random change in the genetic information. (2) There are three types of nuclear mutation: genetic, genomic, chromosomal. (3) Chromosomal mutations caused by changing the order of triplets in the gene. (4) Polyploidy - is an example of chromosomal mutation. (5) Polyploids serve as material for the production of new varieties of crops. (6) Genomic mutations are associated with a doubling of certain triplets in the gene. (7) The mutations result in a change in sign of organisms.
(3) gene mutations caused by changing the order of triplets in the gene. (4) Polyploidy - is an example of genomic mutations. (6) gene mutations are associated with a doubling of certain triplets in the gene.

But the worst results were obtained for the job analysis of the text of sexual reproduction, parthenogenesis, and the laws of variation.

In line 28 traditionally offered genetic problem in the two-hybrid crossover, the inheritance of traits, sex-linked, linked inheritance traits pedigrees analysis. 2018 applicants have coped with such tasks much worse than in 2017.

What are the reasons for this decline results?

Here is an example of one of the jobs with the lowest result.

It is already known. that significant changes in structure and content KIM EGE in 2019 will not be in biology. Only modified model reference line 2 (instead of the two-point reference multiple choice odnoballnoe requested job to job table). Maximum performance of the primary point for the entire work is reduced from 59 to 58. Examples of such tasks are already represented project demonstration version KIM 2019

Here on a positive note concludes my review of the Methodological Recommendations V.S. Rohlovym, RA Petrosova, TV Mazyarkin in guidelines for teachers. FIPI, Moscow 2018. Analysis on biology exams results in 2018.

On my blog you can buy answers to all tests FIPI actual situation review for all the years of examinations and.

"I decide the exam in biology in 2019 for a high score" - so configured graduates who plan to arrive later in the medical, biological, veterinary or environmental departments.

Patience and persistence!

It should be noted that to solve the exam in biology is not so simple. Often, even the availability of knowledge on the subject does not guarantee a high mark on the exam. KIMy prepared by the Federal Institute for Education Measurement, change every year. Changes concern not only the number of questions, but also the structure of the test. For example, last year the time to complete the examination of work increased to 210 minutes. Along with him, and increased complexity of tasks. They have become more objective, and the probability of guessing the correct answer is close to zero. No more questions, that is true only one answer. The first part of the exam, with the proper preparation, not to cause difficulty. The main thing - mindfulness. As practice shows of previous years, examinees do not read into the wording of the job. For example, the particle does not pass. This happens for two reasons:

not enough practice in solving test tasks;
strong emotion.

Prospective applicants must be in the process of preparing to pay attention not only to the study of the theory, but also practice with solving real exam tickets. They can be found in open cans jobs FIPI portal, or other specialized sites dedicated to preparing for the exam in biology. For example, the draft Guschina "decide USE" a lot of attention paid to the preparation of biology. A good collection of the exam tests in biology, and is represented in our training center. We also offer our students to be tested after studying each theme. Proshtudiruyte not only a selection of the exam tasks in biology, but also codificator. It reflects all the elements of the content to be tested on the exam. It is important to choose the current year.

How to prepare and solve the exam assignment?

For the successful solution of tasks of the second part of the pass online tests online exam in biology is not enough. These questions require a detailed response and thorough training with a tutor, teacher or instructor online. The most difficult is the task of Cytology and Genetics. Few graduates successfully cope with them. Would you like to get in their numbers? We invite you to online courses, which contain not only the theory, but also check homework tutor. With the knowledge gained from us, you will easily cope with the problems on the exam and enrolled in university dreams!

And finally. To avoid becoming a hostage of the stress, relax and good night's sleep before the test. Say mentally "I pass the exam in biology," and all you get!

Biology - it's quite a vast area of knowledge that includes the structure and the various processes in man and animals and plants. In this regard, the successful overcoming of the final exam you must possess a vast range of knowledge. Given that the structure of organisms of different species and classes are similar, they do have differences that need to accurately remember answering the test questions. In connection with the complexity of the exam in biology should be prepared more carefully.

Ways to prepare for the exam in biology

For any exam There are many ways to prepare. They differ only technical language and humanities. But the main direction of training sohryanyayutsya. So the exam in biologiine should fall out of the common course of preparing to the exam. An integrated approach to this issue.

Do not forget about schoolwork. In general, the school may be a good idea to prepare the child for the exam. It all depends on his abilities, memory and psyche. So do not write off the school off in preparation for the heavy exam in biology.

When choosing training courses to EGEstoit pay attention to the reviews, and the existence of the office. If courses have opened recently, they have less experience and there is a possibility of fraud or closing courses midway training. But to the young courses of preparation for the exam, you can turn to if they are lured by low prices and they do not have a prepayment. But still carefully talk with teachers and decide: will they be able to prepare you for the exam. On the results of the exam is not worth saving, but we can not completely abandon the services of young professionals. The main thing is not to spend their money wasted.

Tutors biology can pull up the level of knowledge, including help to prepare for the exam. But we must carefully choose the tutor than a training course. Courses received a state license, and passed the test, while private tutoring can engage anyone. So look for references and recommendations before you begin to pay such a specialist. After all, your time is limited, and waste it is not necessary. So it is better to spend a few days in search of a good specialist, what to do with those who can not teach important things.

Test online exam in biology tests

On the educational portal site posted trial versions EGE on biology, are available to all visitors. On our website, you can take the test an unlimited number of times without any time limits. This will identify gaps in knowledge and practice their elimination. So do not forget the self-study. After training exam immerse you into the atmosphere of the test exam, making it more common. Repetition of tests will help to relieve stress on the exam, and that increase the final grade. The stress state of the memory works worse and errors may occur. For this reason, everyone will be helpful to take time for self-training using the online exam in biology tests Uchistut.ru educational portal.
