I taught myself Calc 1, the professor was completely useless. So i didn't go to class, read and did a ton of problems, had a friend who was good with math that i could bounce questions off of, and i aced the class.
As far as a text book goes, i will highly recommend Calculus: Early Transcendentals by Jon Rogawski. Incredible comprehensible writing and proofs.
Also it REALLY helps to have a friend who knows math and can answer your questions from time to time. I mean, it's so hard to teach yourself everything there is that basic calculus has to offer, especially assuming you're only at a pre-calculus math kind of level. You've probably never seen any lengthy proofs, theories or axioms. At least i know i didn't see any of those until i go to Calc 1
