Okay, so I start Community College in late-August. I have hopes to transfer over to the University of Virginia after my first two years. My original plan was to major in Nursing, but I keep being drawn in by the field of Physics, which I see as a HUGE sign to at least reconsider my field of study. So, I flunked out of Pre-Calculus last year for personal reasons (I fell behind due to doctor's appointments concerning my heart, and I don't do well when I start to struggle... I'm one of those people where if I fall behind, I tend to stay behind, but I'm working on it...). For all intents and purposes, you should consider me fresh out of Algebra II. What specific areas of mathematics should I study to prepare for Calculus I? One good thing out of my failed Pre-Calculus venture: I still have my book "Precalculus with Limits", but I would love more online resources if you guys have any suggestions, too. I hate books, but I can keep my eyes glued on a computer and learn for hours. Regardless, I'll use the book if I need to. TL;DR: What specific mathematics concepts do I ABSOLUTELY need/would be super helpful before jumping into Calculus I? If you have any amazing online resources for each specific subject/concept, please post it?
