Boston University chances

I decided I wanted to try to getting into Boston University at the beginning of this year to get a BS in Psychology, I've worked hard to join a lot of clubs, such as DECA (where I'm a 2-year Vice President), theater, SAFE, ect. I've also hosted multiple fundraisers, done lots of community service, and aced every psychology class i've taken, and take all AP and get A's-and B's, along with tons of art classes. Everyone says I have good chances as long as I score well on my SAT's and ACTs my junior year, but how else can I raise my chances to get into my dream college?

thanks for reading!
