Preview & Review

Assignments


Browse your Examkrackers Physics book from beginning to end. Study the table of contents. Read the bold headings and the formulas. Look at the figures. Get a bird's eye view on Physics. (You can do this assignment just as well using other learning materials, such as those from Berkeley, Kaplan or TPR). By the end of this course you will have a strong imprint of what every page looks like in this book. You want to get as many cycles through it as you can.
As in the first module of the course, spend some time practicing with the WikiPremed outline of physics HERE to make sure you can reproduce the outline in full if given a blank sheet of paper. Sit down and try to write it out until you can do it!

Activate      

Goals


Keep working on your ability to outline physics. Make sure you can outline Physics in a clear, conversational manner: Mechanics, Waves, Thermodynamics, Electricity & Magnetism, Light & Optics, Modern Physics, Nuclear Physics and then going further to the subtopic level within each of these topics. Within Mechanics, for example, you have Kinematics, Newton's Laws, Work & Energy, Momentum & Impulse, Rotation, Harmonic Motion, Elasticity, & Fluid Mechanics.
Hold yourself accountable for having a mental picture of the field of reference for each subtopic. Try to think of the simplest situation describing the phenomena. What is the simple model system for each subtopic?

Verbal Reasoning

Assignments


Two or three times this for this module, sit down for one half hour and read from the following works in the category of PHILOSOPHY. With the Santayana, which is a long work, read the first ten pages. Practice reading carefully and slowly. Find the voice in the writing Find the structure of argument. Don't zone out. This is exercise in sustaining attention and concentration. Grip down with your attention and don't let go.

accessibleWalking - Henry David Thoreau
moderateTerminus: of the Interpretation of Nature - Francis Bacon
difficultThe Life of Reason - George Santayana
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.

Activate      

Goals


Improve the stamina of your reading attention. Practice sustaining your focus through dense reading material.
Understand the intentions of the writers of Verbal Reasoning questions on the MCAT.
Verbal Reasoning Tip of the Week
Think for a moment after you read a prompt for an author's tone question. Take a moment to think before reading the answer choices. The shades of difference between the answer choices are usually subtle with author's tone questions. Don't let the answers dictate your impression.
