I just wanted to give my 2 cents on your upcoming CHEM course(s). I have just completed CHEM II, and the best advice I have to give you is to work problems, problems, and more problems!
I usually like to be able to read chapters and understand the topics covered. This strategy is important in chemistry, but reading will NOT be enough. Since it is such a quantitative subject it is really based on solving problems. So do your reading (don't get behind), stay organized, and work tons of problems off old exams (if available), and you will be fine.
Good luck and happy holidays everyone.
