Anyone who is intimidated math, I highly recommend reading through his site. Paul's Online Notes got me through all of my math requirements for my CS program. I would go to my lecture and struggle to understand what was going on each week. When it came time to do my homework, I'd read his notes on whatever class I was taking (Calc, Linear Algebra, Diff Eq) and instantly feel better and have more understanding. I cannot praise this site enough.
