What can I do in High School to increase my chances of college acceptance?

Depends on where you want to go. Local state colleges are mostly just going to look to see if you meet their benchmark test scores and gpa, unless we're talking UT/ UCs and other competitive state universities.

Varsity sports are good, especially if you are really good and can get recruited. It is also good to have a musical talent with accompanying accolades, or to do well in academic competitions like NAQT, History Bowl, Science Bowl, etc. Joining random clubs can be good filler, and getting a position is even better, but if your club just eats pizza and watches movies once a quarter it doesn't matter too much. Just assess what you like doing and what you'd like to try and do your best in whatever you decide on.

A good gpa varies from school to school, but 3.7-3.8 is the lower bound for a respectable gpa at most high schools. SAT and ACT depend on where you want to go, but a 2100+ SAT and 32+ ACT *can* get you in anywhere.
