Review & Preview

Assignments


Study the outlines of Physics, General Chemistry, Organic Chemistry and Biology accessible through the links below. Read them slowly and carefully. Try to picture the model phenomena of importance within each area. Instead of the accustomed learning process in which you add new pieces of material to a series of concepts that grows longer each module, think of studying for the MCAT as a planned process of laying down a comprehensive foundation and elaborating a mental structure through repetition and articulation. Be sure you can reproduce each outline on a blank sheet of paper.

Verbal Reasoning

Assignments


Revisit the WikiPremed treatment of Verbal Reasoning on the MCAT.
Perform Passages 1-10 in ExamKrackers 101 Passages in MCAT Verbal Reasoning.
Go through the test you completed. Label every question by type in the margin: Main Idea, Author's Tone, Thematic Extension, Specific Inference, or Facts & Information. Which types seem to be giving the most problems? In the ones you missed, how do your chosen answers differ from the correct answers?

Activate      

Goals


Remember the five main types of Verbal Reasoning questions.

Main Idea

Author's Tone

Thematic Extension

Specific Inference

Facts & Information

Verbal Reasoning Tip of the Week
Watch out for wrong answers designed to entice you to answer what your own opinion is instead of the author's. The question prompt will not say, 'according to you'. It will say, 'according to the author'.

Essay

Assignments


Read the WikiPremed guide to Writing the MCAT Essay.
Arrange an undisturbed half hour to write an essay. Click Here for your essay topic for module seveb. Don't advance to page 2 until you are ready to begin writing.
You may post your essay at the FORUM for feedback from us and from your fellow students. If you post an essay for feedback, be sure to give your opinion and advice on at least two essays posted by others.

Activate      

Goals


Focus on how to lean a bit towards either the first or the second essay task to give your essay dynamism and unity.
