SAT Biology Format
The SAT Biology comprised of total 80 questions and time allowed to solve all the questions is one hour irrespective of whether you take Biology E or Biology M.
The whole test has been divided into two parts. The first part is Core Questions which comes first. The second part is specialty Questions comes after core questions. The core questions contribute 60 questions and specialty questions contribute 20 questions.
The core section of the test usually consisted of Classification questions (first 10–12 questions), while the last 48–50 questions of the core are multiple choice questions.
Classification Questions
This category provides you with five possible options and then a sequence of three to five questions to which those response options are answered. The options are usually either charts or the group of five relevant biological laws or principles. Because they allow for several choices on the same subject, this category questions will ask you to demonstrate a complete knowing of the subject at side.
The level of problems within any set of choices is usually very random: you cannot anticipate the first choice in a set to be simpler than the last. However, each set of category choices is usually a bit more complicated than the one that came before. In the primary question, for example, you should anticipate question 10–12 to be more complicated than question 1–3.
Completion Questions
These are the multiple-choice questions we all know and really like, and the core of any multiple-choice examination. They ask a question and provides you five possible response options, then you choose the best one.
Diagramic Group Questions
Diagramic group questions present you with an illustration or graph and ask you to identify the structures or functions represented. The questions are all five-choice mcq.
Experiment-Based Group Questions
The SAT II Biology uses group questions based on experiments, natural phenomena, and information to evaluate your biological thinking and skills. There is no conventional overall look for the experiments; the information can be provided in sentences, illustrations, and/or charts.

Scoring
You earn a point for each correct answer and you loses 0.25 for each wrong answer. You loses or gains nothing for the answer left blank. The aggreagte of these score is the raw score. ETS adjusts your raw score to a scaled score of 200 to 800, using a curve tailored to the particular test you take.

This table clearly shows you that your score doesn’t increase with each correct answer. You can do well on the test without answering every question. You must follow an effective strategy that ensures your success.
For example, on an 80 question test, you could score:
- 800 if you answered 79 right and left 1 blank
- 750 if you answered 73 right, 4 wrong, and left 3 blank
- 700 if you answered 67 right, 8 wrong, and left 5 blank
- 650 if you answered 60 right, 12 wrong, and left 8 blank
- 600 if you answered 54 right, 16 wrong, and left 10 blank
Average Scores
The average score obtained by test takers for Molecular Biology is 630 while Ecological Biology it is 591.
Guessing on SAT Biology
Guessing on MCQ based tests is a key element in performing well. If you encounter a question whose two or three options are not eliminated and are competing choices, then you can make an educated guess. As the negative marking is 1/4 in SAT Biology, guessing yields positive results by improving your overall score.
A computer will check your SAT II Biology Test. It does not care how you answered the question it just check whether it is correct or not. So whether you knew the correct answer or just took a guess, you will be awarded one point.
At the Test Center
The test taker is not allowed to use notes, textbooks, or a calculator on this test, even though there are questions that involve math difficult to perform mentally. Although logarithms typically are very difficult to do without a calculator, the usage of a calculator is not necessary as the logarithms are very basic. The only resource a student may use is a periodic table which is provided with the test booklet.
Strategies
Biology is a Theoratical Subject
Biology is a theoratical subject which relies on concepts. Your preparation must focus the learning and less in practicing.
Prep Coaching
Coaching is necessary. You must join some online preparation course.
Be Calm During Test
You must be calm throughout the whole test. If you encounter some hard questions make educated guess but dont be panic. It is not necessary that other questions will also be hard. Maximize your correct answers.
