Depends, do you suffer from anxiety before a test? I recommend Anxiety Free in the days leading up to the test and Personal Genius on the day. (In the morning before the exam). Use Memory Supercharger in the evening after reviewing your study notes. Regardless how you do in the test right after the test (As Soon As Possible) Use Self-Esteem Supercharger that will help for future exams or tests.

If the test has a lot of essay writing Listen to Sales Leap if you have it and when answering the essay questions picture a person you're telling it to. It makes the writing flow.

One Paraliminal that is useful if you van find a corner 30 minutes before the exam is 10-Minute Supercharger. This will life you if you suffer afternoon blahs and the test is in the afternoon. Listen to it and make sure you have 20-minutes before the start of the exam.

And if you don't have time for Paraliminals remember to use the Tangerine Technique it's great for focus especially since you need to read the questions accurately.

If you can sit in the room before the exam get into the Accelerated Learning State as well.

Best,
Alex
