I'm not very mathematical, and I was much less mathematical when I worked that book (calc 1, not calc 2 yet, etc). I found it highly accessible and fun to work through. The concepts are all well-explained and I don't recall anything that would be out of reach for someone with some probability and foundations in classical logic. If they are at discrete math, this book is well withing their reach. It doesn't teach hard math per se, but how to think in a mathematical way, showing how to break apparently diabolical problems into manageable pieces, and how to reconsider the perspective of the problem, if that makes sense. The book is among the most mind-expanding books I've ever read. I'm fully autodidact and far from MIT pedigree.
