any advice for a freshman stats major?

So i started taking courses as a stats major this semester after transferring out of general engineering, and besides the fact that i've pretty much already taken the first 2 intro classes in high school (i took AP Stats) I love it!

I was just wondering if some of the older and wiser people of r/statistics have any advice for what to take or not take, or anything else to do to help succeed at the undergrad level?

I have an idea of what basic algebra-based stats is like from AP Stats, but I don't really know what upper-level courses will be like. (although i somewhat enjoy calculus, so maybe that will help?)
