Don't overdo it

"Always do 20 minutes of each of your subjects every day, even if you don't have real homework in the class. This will keep you on top of the material." - Georgia Bennett, East Hampton High School

Don't be a quitter

"Never give up [on] a problem especially in a subject like math or physics. You can learn so much by determining the answer on your own and you will never forget the difficult problem and how you figured out the solution." - Jennifer McDermott, William Floyd High School

Ask for help

"Don't be afraid to ask your teachers for extra help or other guidance like practice worksheets or review books. Teachers love students that take the initiative in asking for help and are almost always more than happy to assist you in any way possible." - Hailey Wagner, Bellport High School

Don't close the book yet

Schedule a date with your books

Confront challenges with confidence

"Never think that the subject is too hard for you. If you want to know it, you WILL know it. And never hope that the questions will be easy. Be prepared enough to answer hard questions." - Adam Livi, Hebrew Academy of Nassau County

Allow yourself to rest

Get your face away from Facebook

Be unsocial when studying

"Thirty minutes of studying by yourself, without any electronic distractions, can be much more effective than two hours of studying with a group of friends or while on the computer. Even though it may be tedious and boring to study like this, it is a habit that will significantly reduce the amount of time you need to study and improve the quality of your memory of the material." - Joseph Wetzel, Northport High School

Focus on what you don't know

Learn, don't just memorize

Remain calm

Have a higher purpose

It's not about being No. 1
