Answer questions . Even if the material seems clear to you, it doesn't hurt to answer a question asked in class to test your comprehension of the material. If you aren't sure of an answer, make your best guess. When corrected, I can almost guarantee that you'll remember the right answer for the test. Take good notes .
People usually underestimate their capacity to forget material.
Study one hour per class every day . Read the text before class . While reading your text, you should have questions about the material, either in terms of clarification or maybe just elaboration. Jot down your questions as they occur to you so that you can ask the professor when the topic comes up during class. If it doesn't come up and you feel that the question may be too disruptive, then talk to the professor during office hours.
