Verbal Reasoning

Assignments

Two or three times this module, sit down for one half hour and read from the following works in the category of ANTHROPOLOGY. Practice concentrating. Listen to the voice of the writing. Sustain your attention, and don't zone out. This will get easier and easier, as you develop your abilities for mindful reading through practice. Grip down and focus.

Let's practice being an MCAT test writer. In this exercise, write a 'correct' and an 'incorrect' answer corresponding to questions following a typical verbal reasoning passage. Pretend you are part of a committee making the test, and your job is to write a 'best answer' and a 'second best' (tricky but wrong) answer. We will do this exercise often throughout the course to help you understand the nuances of the Verbal Reasoning questions. Print and complete this exercise. Click Here.
