What are some good extracurricular activities I could do as a junior in high school?
In my past years of high school I haven't really done anything other than academics and I want to get involved to help me get accepted into better colleges. I already volunteer, attend school clubs, go to mentorship and college prep programs, and plan to do track in my senior year. What else could I do in my free time?
So my advice is not to choose something based upon what somebody else might think looks good, but instead choose something based upon what you really like. And once you choose that, do everything you can to excel at it. Don't aim for just saying "I did XYZ activity", but instead aim for being able to say something spectacular about what you did.

You're already doing a lot, so I wouldn't add anything to it. Instead think about what can you do better in the things that you are doing? You go to school clubs, but are you a leader in any of them? You plan to do track, but will you qualify for regional or state level tournaments? Etc...

In terms of activities, I would mainly focus on whichever you feel is more related to the career you want as it may come up in the college applications.
Consider participating in a science fair, math competition, or debate club. This can show colleges that you have strong academic skills and interests, and also provide an opportunity to connect with like-minded students. Good luck in finding the extracurricular activities that are right for you!
