Need advice on strengthening high school resume for college applications in the fall

Hello everybody this will be my first post on the WSO forum! 

Bit of background about me: I am a current junior, rising senior in the fall. Obviously since I am posting on this forum I am interested in pursuing a degree in finance and a possible double major in another technical skill.

Now, lets get straight to the chase, here is my current resume and stats, what can I do from now on to the fall where I begin my applications to increase my chances of getting into a higher ranked college

1. GPA (will end junior year with around a 3.83 unweighted)
2. SAT (didn't take yet will take a course over the summer, I estimate I will get around a 1500, if I study very hard maybe a 1550
3. Course rigor
   1. Freshmen year didn't take any aps, nothing really valuable just honors courses
   2. Sophmore year took three aps, calc ab, euro, and ap microeconomics (4 on calc ab, 3 on euro, and 4 on ap microeconomics)
   3. Junior year took four aps, ap stats, ap lang, ap us history, and ap macroeconomics (didn't take the ap tests yet but I think I can get at least a 4 on everything)
4. Extraciriculars
   1. Did district, region, and state level music competitions for soph and junior year and qualified
   2. Qualified for state level business comp freshmen and soph year(fbla); didn't qual junior year.
   3. Worked as a teachers assistant volunteering at a language school for two years
   4. Will work as a intern at a different language school senior year
   5. Was a section leader at my youth orch soph year, probably going to get section leader at a different youth orch senior year
   6. Could possibly get an officer in finance club through connections because my friend is an officer currently
   7. Currently competing in an international essay writing competition, its in progress but I think I can qualify for the final round at least because my writing and research skills are pretty strong
   8. Also planning to start some sort of community service group where we do performances at parks, or something like that in the summer. 

I know this was a lot to read, but I really want to start improving my resume to the maximum for applications in the fall. Thank you in advance for any feedback you may give!
