HABITS OF SUCCESSFUL STUDENTSGet Organized. Making a plan for what you're going to do and when you're going to do it will make sure you're always ahead of the curve  literally. 
Don't multitask. Studies have shown that multitasking is physically impossible. 

Sleep. Getting a good night's rest will sharpen your focus and improve your working memory.
Set a schedule. Do you work better right after school or after you've eaten dinner?  Find a schedule that works for you, and stick to it. 

Manage your study space. Find a place that will maximize your productivity. Look for places away from the television and other distractions. Whether it's your local library or just the desk in your bedroom, set aside a study space that you'll want to spend time in. 
Find a study group. Sitting down with a group of people who are learning the same things as you is a great way to go over confusing class material or prepare for a big test. You can quiz each other, reteach material, and make sure that everyone is on the same page. After all, teaching someone else is the best way to learn. 
Ask questions. You're in school to learn, so don't be afraid to do just that! Asking for help from a teacher, a tutor or your friends  is a surefire way to make sure you truly understand the material.
