I found probability and statistics to be a very valuable thing to learn as well. I wouldn't have done it on my own because it just seemed so boring compared to the other maths(calc, linear algebra, etc...) but it really has a lot of use in those disciplines that you now have the context to understand. Thankfully my college had it as a requirement for cs.
