Ok, I have been to these forums a lot in the past year or so and I have learned a lot and asked a lot. But recently my past year has just been a drag - it is my first year in university and I know that some or maybe even majority will say it is only first year. But I don't think it is that, I think it is the fact that I have done pretty bad in certain courses that I never have before which has only caused me to feel depressed and starting to feel confused (sometimes) for some odd reason. I have always been pretty good at Math, Chemistry and Physics and Biology. I tend to love biology more though which is why I wish to do a Biotech/Biochem degree and then move on to industry. What I noticed this year though is my very small and finite amount of knowledge and understanding in most of the Math oriented courses. Chemistry I did fine, but Calculus I and now currently taking Physics I are both hurting me a lot. I believe it is because as a kid I never paid attention to my studies a lot but I still did well enough to please myself. In essence I WAS one of those students who just studied hard, got good grades, and then forgets everything in the end - and the cycles continued every year. With University though I have noticed how bad this tactic really hurt me, and I would have loved to relive my past 5 years. But since I can't I wish to in a way renew my past knowledge and strengthen it. Although some might say I do not need it, I would love to do it for my own self in order to increase this last amount of self-confidence that I have left with me. So basically I would like to review most of my math knowledge which would help me understand Physics and Chemistry better. I have been thinking of starting from Pre-Calculus, then moving on to Calculus and so on to higher topics as much as I myself can learn. I would love to power-learn or learn quickly although it is still best to go slow I assume. So I was wondering what are some good books to use as review for pre-calculus? I have found a book written by Schaum, not sure if that is an author. So if you guys have any advice on what to use would be great. Sorry for the long post, and if it was a bit boring but I just had to ask someone.
