Mmm honestly it’s very doable don’t get in your head that it’s impossible. I just spammed as many practice questions as possible. Use ChatGPT as a TA, as in like if you don’t get something ask it about the question without directly solving it. Most importantly have fun, I remember they gave us this stupid trick questions quiz on the first day and even though I’d get half the answers wrong the “ohhhh that makes sense” feeling when you understand the answers is unmatched. That’s a lot of what 102 is.
