You didn't mention whether you are a University student or a high school student. I'm going to assume you are in University for this answer.
Since you follow Buddhist ideas, you are likely familiar with the 5 precepts which are voluntarily taken by lay people who wish to follow the Buddha's teachings and who recognize that living in a manner that is harmless to others is needed as a first step. By taking the 5 precepts, a University student would be avoiding some of the worst problems that plague University populations many of which are related to alcohol and drug use and the regrettable behaviors that can follow. Here's a recent example of highly intelligent students ruining their reputations and educational opportunity by engaging in Wrong Livelihood. The practice of sīla can serve a student well and preserve educational opportunity.
The benefits to a student of practicing mindfulness are many and are briefly outlined here from the Brown University Student Health Services page.
Several studies with college students suggest that the practice of mindfulness leads to decreases in stress and anxiety, improvements in concentration and attention, and increases in self-awareness and overall emotional well-being. Professor Willoughby Britton, a clinical psychologist at Brown, has studied the effects of mindfulness meditation on Brown students and has found that meditation decreases anxiety.
Here's enough data to make your head spin from the American Mindfulness Research Association, much of it new and with mixed results. As is often said said regarding following Buddhist teachings and practices, try it for yourself. See if you see beneficial changes in yourself. When you see it for yourself; you'll know. :)
