Hello,
I am currently a junior in high school with only 1 EC (a choral group for 2 years). Academically, I do really well but I have virtually depleted my school of the classes I can take (I did advanced work in 8th grade that counted as high school credit). Does anyone have any ideas of what to do during senior year so that it doesn’t go down the drain?
Note: my school is really small so getting involved with clubs and things like that aren’t an option.
Edit: I will either go to a small private school or be homeschooled. So clubs are not an option either way…
I can assure you that the choir is the only EC at your school. Either way, you’re becoming a senior, so clubs will not have any effect on your application at this point. Why don’t you get a job or do an internship? There’s always a job for high school students. To be completely honest, it sounds like you’re making excuses for reasons that you cannot do things. There plenty of small private schools around me, at least 10, and I can assure you they all at least have 10 ECs. I would get out there and search for something you enjoy and do it. I don’t think anyone can really tell you what to do, because your situation is very specific. Hope you fine what you’re looking for! Good luck! 
Can you take Dual Enrollment classes at a local Community College?
Talk to the GC about options they may know about that you are not aware of…online school or such.
ECs don’t matter as much a course rigor, test scores, and GPA.
Can you be dual enrolled as a homeschooled student? Added benefit would be that you could join some clubs at the CC, for socialization purposes (not for college admissions).
Note that an EC is not necessarily a fun club with your school- it’s anything you do with your time outside of class. So, going to lusuems or babysitting or working a job or taking bird pictures during walks… It all ‘counts’.
So, to make senior year ‘count’, increase rigor junior year by adding some quarter classes from the cc, or summer classes, and get As in your current homeschool classes. Prep for the sat/act. Be methodical about it. You can use Khan academy (it’s free).
You should also look at colleges, not just those you’ve heard of but more broadly - get a Princeton Review’s Best Colleges or Fiske guide and find colleges you like. Go to the website ‘colleges that change lives’ and read up about each college. Run the NPC (net price calculator) for each college - you’ll see they each offer different net costs even if you input the same data, because they count assets, income, equity, etc, differently.
