Hi, So the last time I grabbed a college-level book was 2 and a half years ago. In October/2016 I am starting my bachelor of science majoring in Electrical Engineering. So I have plenty of time to recover the flexibility of my brain. First of all, I need to get a fresh restart regarding the "Pre-Calculus" area. I am considering the book "Pre-Calculus Workbook for Dummies, 2nd edition" https://www.amazon.com/Pre-Calculus..._UL160_SR127,160_&refRID=144FBKBG30WQFDMXNYW4 Do you think it is a good book to refresh my mind or there are better options out there? The thing is, there are some Pre-Calculus books consisting of more than 500 pages and honestly I find it kind of absurd ! Also, what are some Must-Read books before enrolling in an EE program ? Some have told me, the Art of Electronics is a Must. What do you think ?
