I have always loved calculus from the time I first knew what it was. I want to learn and explore calculus by myself (I know stuff like differentiation, integration, limits, etc, which is very basic). I also want to learn extra stuff like multivariate calculus etc. I have Thomas' calculus ( by Maurice D. Weir) and Apostol calculus.
So all I want to know is
how much time do I spend for calculus everyday, how do I go about the topics and are there any other books and websites which I can refer to apart from the ones mentioned above which will help me in my learning process?
