For calculus, I'd skip the more physics like finding of integrals and derivatives. What matters is understanding the concepts of integrals and derivatives, and knowing properties like the chain rule. It pays much less to know that the integral of 1/x is ln(x) (or the other way round).

The linear algebra and probability theory are most important imho. I'd also distinguish between probability theory and statistics. Both are important, but they are distinct disciplines.
