Set a time during your day to look through ALL your notes. Make up acronyms or ways to remember something that's important to know. Read from your book on the things you're still confused about; your book should explain the topic in more depth. Make flashcards. You can actually make online flashcards here: http://funadvice.com/r/15renqvuf2q. It's super easy and helpful. Also, I'm sure you can find tons of practice problems online to do. If you're totally lost, go in to school early (or stay after) to get extra help from your teacher.
Look at your information, make flashcards, make up tests then try to figure out the answer, have study buddies, have family quiz you. There's a lot you can do you just have to be prepared.
I don't think flash cards help much for physics
Okay, well that was just one idea haha.
