Physical Sciences
--
Physics - for this class, do as many practice problems as possible until you can tackle any question based on the topic at hand. Physics24/7 -- Comprehensive physics help - it breaks down concepts very well.
-- Chemistry - follow the examples your professor gives in class closely, then be able to write your own questions based on these examples. Only then will you really know chemistry.General Chemistry Online - This website is awesome - Start with the companion notes, then use the tutorials, you'll find yourself learning without really trying. It is essentially an online textbook that is easy to read. Biological Sciences
--Biology - memorize all of your notes for this class and you will survive.The Biology Project -- Boom. University of Arizona's biology website.MCAT hormone flashcards -- self explainable.
-- Organic Chemistry - Study this class every day - it is known to be very challenging. I recopied my notes every day in this class. Know each new reaction, how it can be used, and if taught, know the mechanism. You will have the knowledge to synthesize a lot of important compounds from scratch, it is very interesting course if you consider what organic chemistry does for the world.Organic Cliff notes -- Everything you need, when you can't understand your professor.
