Am I on the right track to university?

You're an all star and the only thing you might need help on is essay writing but I can't reall say that because of course I don't know you. I do know the essays mean a lot to an admissions office, even as much or more than the SAT and similar scores. But I'd say just from what you've written here that you are a top candidate for any college and you should now be actively exploring the scholarships and grants that you might qualify for at your chosen schools. There are a lot available but the competion is kind of fierce. You sound like you'd be one that would win scholarships. Your resume sounds pretty good but remember, the essays mean a lot.
