I guess you like shonen?
Well, most of the popular ones...you should like.
Naruto, Bleach, One Piece, Fairy Tail, Fullmetal Alchemist (can help you with chemistry...sort of), Nurarihyon no Mago, Hunter x Hunter, Katekyo Hitman Reborn...and if you like card games...Yu-Gi-Oh (i prefer the manga), some of the new ones: Tonari no Seki-kun, Sword Art Online...those popular ones are what your age boys should like.
(But if you're talking about me, or people older, then my preference would be much different--like Death Note, Another, School Days, Parasite, Attack on Titans, Code-Breaker, Psycho Pass, Tokyo Ghoul, Ansatsu Kyoushitsu, Ouroboros...etc)
If you can take romance, then I have a bunch more to recommend.
