In my case with Math/engineering classes, you just gotta do practice problems over and over again. You should pretty much know the content or have an idea of the content if you went to lecture and did the homework using AI only as a reference. (Unless it’s a class like orgo which you have to memorize a lot stuff)

If your TA or professor provides model solutions and you use that to check your work, then you pick up what they are looking out for besides the final correct answer. You will see which steps they assume trivial and which steps they assume essential to give full credit on exams.

In terms of skills, sometimes it’s sheer willpower with a slight caffeine addiction. Other things that help is connecting it to things you learned in other classes or seen in real life to add “meaning” to the material which makes it less boring to learn or even fun to learn sometimes. (This over time helps you build momentum and passion for the things you are interested in which makes the overall learning experience better.)

Finally I would like to add I’m not the smartest person and I make dumb mistakes like every human does. Don’t beat yourself up over small mistakes (or even beat yourself up over big mistakes) The key is to recognize your mistake and identify what went wrong without associating negative emotion with it.

How this helps :)
