Thanks for your reply, ucbalumnus.
It’s been almost 10 years since I last took Calculus (which was a non-rigorous sequence - I don’t recall doing any proofs, just plug and chug). I’m concerned that if I don’t retake those courses (a rigorous sequence) I’ll be at a severe disadvantage doing any upper division math, and not really be satisfying my goal of getting better at using math in my everyday work.
Likewise, skipping ahead to upper division CS seems unwise given I’ve no formal algorithms/data structures/computer organization courses.
By the way, my only option at the moment (family and job keep me here) is University of Oregon.
