It is too late to reach the teacher or to get a tutor. There is not even much time to think through the material. However, by beginning study a week early, by going through text and notes once, students can see which items they know and can get together with other students, with the instructor, or with a tutor. They can have the time to think out the problem themselves. All course material is not equally important.
Instructors frequently ask the same types of questions again.
For example, if an earlier test contained several researchers' names, later tests will do the same. If an earlier test contained many questions on theories, the later ones will too. Use your answers to previous test questions as guides for your study. Now you're ready to actually begin studying. Go through all of your material once.
