The library is full of free resources people forget about — encyclopedias, reference librarians who will literally do research for you, study guides. And the librarians are thrilled when someone actually asks for help. Don't be shy about it.

The standard advice on this is actually pretty good. But what nobody tells you is that consistency matters more than intensity. Studying 30 minutes every day beats cramming for 6 hours once a week. Build it into your routine.

Teach it to someone else, even an imaginary student. If you can explain a concept simply and out loud, you understand it. If you stumble, you've found the gap you need to study. They call it the Feynman technique and it really works.

Flashcards still work. Old-fashioned index cards. Make them yourself — the act of writing the card is half the learning. Quiz yourself, shuffle them, put the hard ones in a separate pile. Low-tech but it gets results.

There's no one-size-fits-all answer here. Experiment with different approaches and pay attention to what actually works for you, not what worked for your friend. Learning styles are real — some people learn by reading, some by doing, some by listening.
