Hints: work-study 文中一句话加括号，另外有一处破折号。
Take good notes and study them regularly. Because there are so few tests (usually no more than two or three plus the final exam), they will cover work done over a long period of time. Only by taking and then keeping up with your notes can you study effectively for theses tests. Seek help when you need it, before it's too late. If you have special problems, don't be afraid to seek help. See your teacher, your advisor, anyone that you think may be able to help you. It is important that you be aware of where you can go for help. And most campuses can help you with money – student loans, scholarships, special student aid funds, or work-study programs. Find out what is available at your school, and be prepared to use it when you need it. Attend classes and be active in class. Attending class and arriving on time are important points to show that you are serious about your learning. You should take part in classroom discussions and hand in assignments on time. Speaking up in class forces you to think about what is being discussed and keeps you interested in it.
