Although the options are not included in this question, we can still figure out some effective ways to get ready for a test.
One of the most important ways to prepare for a test is to review the list of subjects that will be present in the test. This will allow us to identify the parts that we know well and those which we need to study more carefully. It will also help us focus our attention on the right subjects.
Another strategy would be rereading our notes. Even if we feel like we already know a subject, we can always benefit from a quick read through our material.
Finally, a useful strategy is to focus most of our attention on the subjects that we find particularly difficult or unclear. This strategy is even more important in cases when we are short of time.
