What Are My Chances in Getting into Good Universities?

So, throughout high school I never committed to any clubs or sports or activities really. I dabbled in law club, art club, interact (a volunteering club)… but, I never sticked with one club throughout the year until junior year when I joined medical science club and I stayed in that for the entire year. I did work the summers when school was out as well. However, since I did get good grades (3.9 unweighted gpa and 4.6 weighted gpa) I got into the national honor society at my school and I love it! I love tutoring and volunteering but the bad part is is that I did terrible on my act. As a senior, I can’t really change my ACT score anymore at a risk for missing deadlines so I’m trying to get into more clubs and extracurricular things like that but will I even get into a “good” university? I just don’t know my chances because I never was committed to one thing and my act score doesn’t match up with my grades…

Forget about the clubs. Get our score up.
