There is a reasonable, logical, and effective method of test preparation. Learning occurs in repeated practice. Your efforts should focus on understanding the material and remembering key points or definitions. All initial learning should be completed at least 48 hours before the test. That revolutionary concept is the foundation of the preparation phase.
Preparation begins with an analysis of the domain of the test.
Assemble your class notes, texts, handouts, and so on. List all the topics you believe the professor might use for test questions. It is crucial that your list is complete so take the time needed. Look over your list. The final result of your reflection should be an exhaustive list of topics.
