Do you exam well? Like are you calm sitting them, do you know how to keep track of time and avoid sunk costing on questions you can't answer etc?

If no you'll want to address that.

Otherwise work through textbooks of the appropriate material. Find some and work through, I mean work through. Not speed read and nod along. Write notes and do the practice problems. Do it regularly, to learn how to do a skill you have to regularly practice. You'll need a schedule that has you setting aside time at least a couple of times a week.

You have to regularly practice things in short sessions to learn well, and once learned repeat less frequently to maintain that knowledge. So you might spend 1 hour on the current topic, and close with 15 minutes of some practice questions on topics you already covered.

Keep notes of what you've done, by hand! it activates more brain shit. Talking aloud through problems can help too, or pretending you're explaining what you just learned to a nearby prop or very patient person. If you're struggling with a topic in your revision questions do more of it till it's easy again.

Also I don't exactly recommend this but amusingly prompting an llm to be an inquisitive listener and trying to explain topics and answer its "questions" might be helpful? NEVER try to learn from one though, they lie really convincingly.
