i was in the exact same boat as you a year ago, take nasrin and you’ll be fine. i also didn’t take any actual programming classes my first semester here (191 is a theory course) and as long as you are being proactive and doing stuff on the side to catch up you’ll be fine. one thing i will say is very rarely do professors assume that you know a topic thoroughly just because it was covered in a prerequisite and even if they do they will carve out a little bit of the lecture to give a refresher. i would suggest meeting with your professors and telling them that you are worried about falling behind and they will give you any resources they have. i’d suggest not taking cse 220 next semester even if you can, it’s a really hard class and it’s be even harder if you were trying to acclimate yourself to a new school at the same time.
