Focus

This is the single most important strategy for success in both high school and college (and at work). Focus on what you want, on what you are doing, on where you are at the moment. If you are in college, focus on each and every class and assignment. If you are in Chem I, focus on that class, that assignment, that grade. Dont let your attention be diluted with outside interests until your schoolwork is completed. You wont do well in International Politics if you are fighting with your significant other or worrying about what to wear to the football game this weekend.
