You should take very good notes everyday and re-read what you did in class. It would be to your advantage to make flashcards. You can make flash cards on paper, studystack.com, and other apps you can download to your iPod, phone or other technological devices. Go to the after school study sessions and ask questions when you don't fully understand something. Listen to Mr. Brock talk everyday and have class decisions about the topic that you're learning about. When you make a poor grade on a assignment and have a opportunity to redo it for half credit, do it. If you have a low grade it is definitely hard to bring it up. Study as much as possible, and dedicate time to this class.
