If you are studying to this music, try this also. Find a small piece of scented candle or scented soap, make sure it is a scent that you never used before. Bring the candle out to smell while you are studying for a subject and put the candle away when you are done studying. During a test or exam, bring out that same piece of candle (or soap). You will be surprise on how much more you remember. Very important, it has to be a unique scent that you do not smell anywhere else. Use a different scent for each subject. Perfume works too but they are more expensive.
