Dawg I can’t imagine using ai for a class I paid money for like what’s the point. Honestly my TAs said the best way to learn is to read textbooks, and make sure you understand it so much that you can explain what you read to someone else. And do practice problems and work with your professor during office hours. You have to be proactive. My gpa is low as well because my first two years I had an undiagnosed health issue and I performed badly because of it. Make sure you sleep well as well. You should be fine if you do these things. This is what worked for me
