Hey OP–don’t worry too much! I looked at one of your other threads, and I think you’ll have a solid application, especially as a writer (nailing essays can give you an edge at competitive schools). A 3.4 is NOT a bad GPA! And you don’t know what the next two years will bring–I saw you want to bring it up to a 3.5, and I don’t see why you couldn’t. Focus on your studies, and don’t stress out too much about ECs. Looking at what you’re thinking of doing, I wouldn’t stretch yourself too thin, especially if you a) aim to bring up your grades and b) you’ll be waitressing in grade 11 & 12. It’s not easy to balance a PT job as a high school student AND get good grades AND do ECs. If you need the spending money from the job, prioritize that over resume filler via after school clubs. It seems like you’re into volunteerism, which is good–I would do the Key Club for sure–and doing an additional volunteering thing, particularly if you’re passionate about it, is a good idea, too. I’m partial towards the animal shelter–I did volunteering at one and it was awesome. I would join any writing clubs your school has too, but nurturing that talent outside of school also counts.
Are there any local programs for writing you could do something with? Writing contests you can enter? What kind of writing do you do? Writing is an EC, even if it’s a difficult one to show on an application. Look into the Scholastic Key awards, and also if there are any local programs, like a summer writing camp or intensive that you could attend. (where do you live? Maybe we can help you identify options)
The important thing is not to over-focus on dream schools, like NYU. I saw you are looking for scholarships, so honestly it’s best to let go of the NYU dreams now, because they’re very stingy. But you’ll be a solid applicant for a lot of schools, don’t worry. Especially if you plan on applying to do a writing-related major, you may qualify for special grants and merit scholarships. You’re a URM, as well, which will work in your favor at many schools, including the elites. Focus on getting a good SAT score–take it as soon as you can (if you start studying now, you can take it in the fall. Once you have your scores and you see your grade trend as a junior, CC can help you put together a realistic list and help allay some of your anxiety.
Deep breaths! You’ll be OK!
