Tips for a new player?

So I'm trying out for my high school team and haven't played since little league. Try outs are in a few days and I was wondering if you guys have anything I should work on before try outs and anything that will help in try outs

Update: just finished the first day of try outs and I'm fairly happy with how I did! And as a bonus I beat everyone in the confitioning!

Update #2: Made it! Thanks for all your help guys!
