You might think of them as little quizzes, which you can use to hone your skills. Whether you need top MCAT tutors in New York, MCAT tutors in Chicago, or top MCAT tutors in Los Angeles, working with a pro may take your studies to the next level.
MCAT Biological Sciences Section
What does the MCAT Biological Sciences section cover?
The MCAT Biological Sciences section can be broken into two generalized categories: organic chemistry and biological sciences. When taking this section of the MCAT, test takers are often presented with passages that provide highly specific details about complex biological functions. Questions then require test takers to integrate the provided specific information with generalized biology concepts to draw conclusions. Material in this section includes organic chemistry reactions and mechanisms, cell biology, molecular biology, evolution and genetics, systems biology, and some biochemistry. Varsity Tutors offers resources like free MCAT Biology Diagnostic Tests to help with your self-paced study, or you may want to consider an MCAT Biology tutor.
How many problems are on the MCAT Biological Sciences section, and how much time do I have to complete them?
The MCAT Biological Sciences section consists of 52 questions. 70 minutes are allotted for this section. Approximately 40 to 45 questions will be based on passages, and the remaining questions will be stand-alone questions that do not have any background information provided.
Should I guess on the MCAT Biological Sciences section?
There is no guessing penalty on the MCAT. Scores are based on the number of questions answered correctly, and are not affected by questions skipped or answered incorrectly. It is a good strategy to answer every question on the exam, even if you must guess.
What kinds of problems are on the MCAT Biological Sciences section?
Questions in the MCAT Biological Sciences section can be passage-based or discrete. Discrete questions will generally be straightforward, asking for identification of biological terms and concepts or conclusions based on one to two sentences. Passage-based questions vary in content and structure. Some passages provide information about certain processes, while others provide experimental setups or data for analysis. Be prepared to identify new information that is provided in the passages and draw connections to your experiences with college coursework and material. Many questions will require application of general biological concepts to specific scenarios described in the passages.
How can I prepare for the MCAT Biological Sciences section?
Varsity Tutors’ Learning Tools feature Full-Length MCAT Biological Sciences Practice Tests to assist you in evaluating your overall preparation level. The exam simulating format of the complete practice tests can guide you in learning to pace yourself in order to ensure you’ll have enough time to finish the entire section. These free Practice Tests can also assist you in building a personalized review plan, as the results page will reveal which of the concepts you’ve already mastered, and which concepts may need some additional review. The results pages for the full-length tests also offer other helpful study resources, like clear, detailed explanations of the correct answers and links to additional online study resources. After you’ve done a thorough review, you can assess your knowledge by taking another Full-Length MCAT Biological Sciences Practice Test to check your progress. Other free MCAT Biological Sciences Practice Tests consist of a concept-specific selection of 10 to 12 questions, which will give you a cross-section of topics from the Biological Sciences section of the official MCAT. You might think of them as little quizzes, which you can use to hone your skills. In addition to the MCAT Biology Practice Tests and MCAT Biology tutoring, you may also want to consider using some of our MCAT Biology flashcards.
