You can be an excellent student who does all the tasks and pays attention to all the explanations, but if you don't study for the tests in advance you won't be able to apply your knowledge. A good student should create syllabuses that help him summarize the required subject and create a schedule so that he can review this subject prior to testing in advance and calmly. This way he will be able to learn the whole subject and keep the knowledge necessary to succeed in the tests.
