Hey man I have tried several methods of learning on my own. I have done it without having previous knowledge, however. This means you can examine these tools à la carte. Khan academy has been the best resource for finding explanations of, great bit sized chunks for easy ingestion. I am not a fan of there tests/quizzes. I have found as a novice in the subject made it difficult at times to do the problems. These were caused by some problems containing more advanced/or unknown rules. For finding resources on practice I would recomend
http://tutorial.math.lamar.edu/Problems/CalcI/CalcI.aspxIt has everything you would learn in a calculus 1-3. It has explanations, cheat sheets, and tons of worked problems. Use these to brush up on what you know and challenge yourself on what you do not OP. Good luck on you're exam
