Didn't take a single foreign language in HS

I agree that many students, being that they are young teens with immature brains and inexperience, often think that doubling up on their “intended major” courses will be best and they basically dont listen and ignore any advice early on that says otherwise. Sadly, there are very few students who become the exception and that doing the doubling up actually is helpful. Also sadly many of these students often have parents who will only “accept” T20 schools. I feel for those kids.
Truly hoping OP can do some of the suggestions and get into a school that is a good fit for them!
