If you are talking about High School wrestling, I will let you know right now that they aren't the most compatible styles to use. Generally speaking, the games are much too different.
In wrestling you are going to be concerned with takedowns, riding and pins. Those are generally universal aspects in the grappling game that carry over well to BJJ. Most of the time that's where the styles stop complimenting each other.
For instance, in wrestling you never go to your back. If you do, that's a pin and you lose. In wrestling, there may be some turns and pinning combinations that are painful for the recepient, but there are no true "submission holds." If you put on a neck crank, choke, armlock or leglock in wrestling, you'll get DQ'd.
Generally speaking, if you are already in BJJ and you are going to start wrestling in High School you are going to have a few things going for you right off the bat:
1) Your conditioning should be better than normal.
2) You should be comfortable with moving and scrambling on the mat.
3) YOu should already have a fundamental grasp of takedowns and how to control/ride your opponent.
However, if you keep in mind that the game of one is completely different than the other, you might find yourself falling into habits that don't carry well. If you roll with the differences consciously upfront in your mind, you shouldn't be at a horrible disadvantage. You are just going to have to stop and take a second before you notice your opponent is feeding you an arm or a choke.
It doesn't matter if you agree or disagree
