Preview & Review
You have now taken three practice exams over the past few months. Each exam has been preceeded by a substantive, comprehensive review cycle in which you looked at the fundamental principles you need to know for the MCAT from beginning to end. One of the things you should be noticing at this stage is how much more quickly you can cycle through the material now that you have done it a few times than you could a few months ago, and you can still comprehend it. It is beginning to seem like less material. You should be starting to sense how the body of fundamental concepts is becoming less imposing as you can now grasp the structure of the knowledge and are familiar with the half dozen main concepts within each chapter. You are getting past it. Take advantage of this ability in the last few modules to get as many cycles through the material as you can achieve. In this module, take one or two hours for each discipline and make a solid review cycle, taking five minutes for each main topic, holding yourself responsible for the five or ten main concepts. Open up ExamKrackers, your WikiPremed book, your Concept Map, the Learning Center, your Physics Cards, your textbooks and force yourself to step into the field of reference for each topic, inventory the main ideas, and move on. Get through it.
Be able to comfortably navigate a comprehensive review cycle in no more than five or six hours.
Be prepared name the five or ten main ideas within each of our 99 topics. (Use the topic outlines within the Learning Center to check yourself).
Read the Coaching Discussions associated with the Main Progression topics of Electricity, DC Current, Magnetism, Electromagnetic Induction, AC Current. Start HERE and proceed by clicking the right arrow.
Possess mastery of the use the classical language of electrostatic potential energy to describe changes in the internal energy of matter at the atomic level, molecular level, and intermolecular level, keeping in mind that quantum electrodynamics provides a more complete description.
Be able to conceptualize the intersection of electric and magnetic phenomena in a broader discussion of electromagnetic induction and light propagation.
Feel comfortable translating the physical quantities applied in DC Circuits to the stoichiometry of electrochemical cells.
Have fluent intuitive discourse between discussion of electric potential and energy in DC and RC circuits and mechanical work & energy.
Be able to relate capacitance as a general concept describing the relationship of charge geometry and the potential function to the interpretation of internal energy in chemical systems.
Be prepared for questions involving the kinematics of accelerating charges where the direction of velocity is changing in the context of magnetic force.
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.
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.
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.
