One of the main ways to be successful is to study. If you have an exam coming up and you're not really sure about a certain topic, study it. Be sure you study thoroughly for each exam or you're going to be in trouble. Be sure to take many notes in class and don't be afraid to ask questions if you're not sure about something. Be sure to go back and use the flashcards he made you do. Trust me they work. If you study effectively and get good study habits you will be a superstar and rock the tests.
