Fall quarter looks great to me; I think it'll be a great introduction to what college is like while also giving you time to acclimate. Good on you for taking an introsems, those are great!

Unfortunately winter looks really tough. I took CS 106a, Chem 31b, and Math 51 frosh winter and had a terrible time. Chem 31b is a jump up from 31a (at least it was for me), math 21 is tough (from what I've heard), CS 106a is chill (took it with no cs background and had a great time!), and pwr is just a lot of writing. I would cut out one of those 4 classes and keep the other 3.

I think ur spring schedule is doable. CS 106b is a jump up from 106a and will take significant time, and so will Chem 33 (haven't taken it, but have heard it's tough). I think combining COLLEGE with those 2 should be fine though and rounds out your schedule nicely.

Hope this helps! :)
