Master the Concept and Question cards for Modern Physics from the Learning System for Physics. The first half dozen cards, which deal with special relativity, are optional.
Look over materials you covered earlier in Atomic Theory, which has significant overlap with Modern Physics. Here is the Atomic Theory Conceptual Chapter, the Atomic Theory Problem Set, and the Answer Key.
Finish your Main Progression work on Modern Physics with a review tour of the Modern Physics external resources in the Learning Center.

Be ready to solve problems involving the basic apparatus for demonstrating the photoelectric effect and interpret results to determine the work function.
Possess a basic familiarity with the Compton effect so that you would be able to navigate a passage dealing with it.

Regain your feel for Molecular Spectroscopy by browsing the terminology and images within your Learning System Book, complete the basic terms Crossword Puzzle (Solution) and perform an online drill at the Question Server.
Read pp. 89-96 in ExamKrackers Organic Chemistry and perform the questions on p. 100 (The discussion also deals with some other lab techniques)
Take a careful review tour of the Molecular Spectroscopy external resources in the Learning Center. The spectroscopy discussions in the Virtual Textbook of Organic Chemistry are perfectly attuned to the MCAT.

Goals


Understand the mechanism of IR spectroscopy in the vibrational excitation of covalently bonded atoms and groups by electromagnetic radiation in the infrared portion of the spectrum.
Be familiar with the meaning of reciprocal centimeters (cm-1) on an IR spectrograph.
Be able to predict how changes in the strength of a bond or the mass of bonded atoms would alter the frequency of absorption in IR spectroscopy.
Be familiar with the fingerprint and group frequency regions of an IR spectrograph and be able to recognize the half dozen most prominent types of stretching vibrations in the group frequency region by frequency.
At the basis of nuclear magnetic resonance spectroscopy (NMR), comprehend how the presence of an external magnetic field will result in the existence of difference spin states for a nucleus with a net magnetic moment.
Understand how the location of different nmr resonance signals depends on both the external magnetic field strength and the rf frequency in the context of shielding by extranuclear electrons. Understand what it means to refer to chemical shift in units of ppm.
Be able to use the electronegativities of bonded atoms to judge the extent of deshielding in proton NMR, and recall that pi electron systems can effect chemical shift by supporting or opposing the external field.
Remember that adding heavy water to a sample under proton NMR makes acid protons disappear from the spectrum.
Know how to interpret structural information from the signal splitting resulting from spin-spin interactions in proton NMR.
For UV spectroscopy, understand the electronic mechanism of absorption of electromagnetic radition in the context of molecular orbital theory and comprehend the role of conjugation in shifting absorption maxima toward longer wavelength.
For mass spectroscopy, you should be able to describe the basic mechanism of ionization, ion sorting under a magnetic field, and detection.
In interpreting a mass spectrum understand what is meant by the base peak (sometimes but not always the molecular ion).
Understand the distinction between even-electron ions and odd-electron ions and have a reasonable understanding of fragmentation patterns in mass spectroscopy.

Preview & Review

Assignments


In this module you take your fourth scheduled practice test. The Preview & Review component this module is dedicated to comprehensive review in preparation. Using your past three practice tests, ExamKrackers, WikiPremed materials, any other MCAT books, online resources, and whatever other study materials you prefer to finish preparing for your fourth practice test this week.

Activate      

Goals


In finishing preparation for your 4th practice test, concentrate on the sense that whatever types of phenomena an MCAT passage is dealing with, from the physical and biological sciences, you can find your footing to orient yourself in the fundamental principles.

Testing

Assignments


It is time for your first practice test. Hurray! By far the best practice MCATs are located at the AAMC site www.e-mcat.com. These are real computer-based MCATs created by the test-writers themselves with explanations and detailed score reports available. Although one test is free, the service is kind of expensive (boo!) but you really should use the facility for at least two or three of the practice MCATs scheduled in this course.

The MCAT is a five and a half hour test with ten minute breaks between sections: physical sciences (70 min), verbal reasoning (60 min), writing sample (60 min), and biological sciences (70 min). Set aside six or seven hours when you can guarantee you will be undisturbed. Secure pencils, scratch paper, and a clean desk with only your computer. If you have a WikiPremed study group, try to arrange for everyone to take the same practice tests in the same order so that you can discuss them together. Good luck!
As you begin reading each passage in the science sections, practice orienting the subject matter within the outlines of the sciences you have internalized. No matter how dense or difficult a passage seems, the questions will be about fundamental principles. It is a rule that the harder the passage the easier the questions.

Goals


The score you make on your first practice test is NOT the score you will make on the MCAT. It's good to do well, of course, but the main purpose of cramming for this practice test has been to make you get through the material at least one time. Your learning goal is to begin to take comprehensive responsibility for the knowledge.
When you go through the solutions and score report, try to gain as much insight into your strengths and weaknesses. However, take this with a grain of salt. There aren't enough question instances on an MCAT for fine-grained diagnostics.
Understand the MCAT pace and the nature of MCAT passages and questions. The MCAT is a good test. The more you understand the point of view of its authors the better you will do.
