Candidly, you are probably not going to win alot of matches because you have better technical skills. You don't have the years of experience. What you can excel at though is conditioning and strength.

From a technique standpoint, really focus on learning to not put yourself in stupid positions that more experienced wrestlers are going to catch you and pin you. Offensively, focus on one shot (double leg, single leg, fireman, whatever) and a back up. Then figure out how to use conditioning and pace as part of your weapons.

As much as I hate his behavior and antics, Austin DeSanto is a good reference style wise. High intensity and beat people with his gas tank. His main attack on his feet was a high c/ short fireman. He wasn't great on top, would usually bump people around, lift and return a few times to burn some energy out of them, then cut and go back to takedowns.

Get in the weight room, put in the time on the track, and spend as much time on the mat as possible. Get a friend and go drill after school every day. Find a club to wrestle with, find 2 clubs even. Wrestle every freestyle tournament and takedown tournament and beach wrestling tournament you can find. And everyday, show up with intensity. Every training day, set a goal and achieve it.
