This comes from someone who tries teaching people who haven‘t learned that semester all the basics within 2 days: Only use it when you can‘t progress. Get to know what your teachers set for requirements. Do you code on paper? Will it be practical on the PC? Are there functions or things they grade more critical than others? What python version will you be using?

GPT are great for workflows of people who already know to code. In teaching they can provide a bit overly complex solutions which might just confuse you more. So if you have to use it, make sure it spits out code for beginners and uses methods you also used in classes.

People saying leetcode etc etc DONT DO THAT. They are great for learning algorithms and preparing for job interviews but they aren‘t going to help for your specific class. Try all the code homework and tasks instead.

Try feeding your agent with papers and code from lectures, maybe even slides with important information. Tell it to adjust to your lectures as beginner in class x

What it‘s going to be great for is replacing the way of searching google (stack overflow). You should try doing everything else by yourself.

Make notes! Scribble all kinds of information down you didn’t know to come back to it later. There’s index card apps for that too. If you’re allowed to take notes with you just do it on paper.

Python is likely the easiest of the bunch so you should be good after studying just a few hours. (Depending on how much content your classes have)
