TIPS:

Solve Homework problems regularly. Read the material covered in immediately preceding classes before coming to class. Ask any questions you might have timely and do not wait until the last minute. Discuss the material and the homework problems with your peers and make use of the free tutoring center offered by the Department of Mathematics. Use homework assignments and quizzes to test your understanding of the material and your ability to solve problems within a time constraint.
