Trying to "beat the test" is never a good strategy. In some cases, there may be some strategies like cross out the obvious incorrect answers, or read the answers first, etc. But this is a math test. The easiest way to pass a math test is to know how to do math.
You have already taken the test. You know what type of material is presented and how it will be presented. You know what areas you were less comfortable with. Go back to your basics and just practice.
