You have good grades and a couple of extracurriculars- this is an excellent place to be in as a sophomore. I’m assuming you’ve been looking at the stats seniors like to post concerning college admissions. While it’s good to have some idea of what colleges like to look for, you can’t assume you should be at the level of a high school senior when you’re only a sophomore. You still have a few years to deepen your extracurriculars, try for leadership positions, or win awards. Just chase things your passionate about and try to have a concrete result by December of your senior year.
