It all depends on how motivated you are, but you could buy the Schaum series book with 3000 problems in calculus, and get through some reasonable portion of them. You should do most of the problems yourself. Reading math or reading someone’s solution doesn’t work. I mean you can look up the first few solutions. There are solutions for every problem. As a soccer coach once told me, there is no substitute to touching the ball. As many times as you can. This will fix your calculus problems.
