How should you study? How should you learn? Everyone says “study harder?” Here are some thoughts and some specific ideas.
When your background knowledge isn’t there, learn it and master it.
When you make a mistake over and over, put up a red flag for that kind of thing in your head, and be slower and more mindful whenever you’re working on that thing.
Be neat and organized.
Ask questions of yourself to pull things out of your memory and help you think through things.
Work harder problems, not just easy problems.
Make up the material meaningful.
Ask other people for suggestions and advice.
Get plenty of sleep.
