Shoud I take 4 years of a language in highschool or will 3 years in middle school be enough?Answered
I took French for 3 years in middle school and am planning on taking Spanish for 2 years in highschool. Would that look good on applications?
The best transcript has 4 years of 1 language on it so if you are taking Spanish in HS, take Spanish 1,2,3,4 or AP Spanish. Or just take French 4 and AP French and be done with it. Having 3 and 2 is not the same 4 of 1 language and possibly taking the AP in that Language IMO.
This is what a college like Harvard would like to see.
Then the next best would be to take 3 years of 1 language. This is what most Ivys and Elite college would like to see. (so you are on track for that).
If you are applying primarily to Top 50 - 100 schools or Large public universities like UC Schools, then 2 years of a language is acceptable, 3 preferred.
When you are planning out the rest of your curriculum remember that you are striving for (5) 4s which is 4 English, 4 Math, 4 Science, 4 History, 4 Language (if Harvard is your goal).
Hope that is helpful and good luck with the rest of your high school career.
