During the recent admissions season I was accepted to Yale (early action) and Columbia (via likely letter) along with a number of other competitive universities. I only took 2 years of French in high school.
I don’t wish to discredit the advice that many of the people are giving you. Taking 4 years of a language is great and can look great on your college application. However there are just so many other components to a persons college application that you shouldn’t get caught up in minor things like that.
Junior year I had to decide whether I would take 2 science courses or continue on to French 3. Since I saw that the level of French I could reach in hs was limited I chose the 2 sciences. Avoid getting caught up in all the chatter telling you to do what I think are unnecessary things to impress college admissions officers (like studying a language over the summer).
If you hate Chinese then don’t take it. Use your time to do things that you like. I think as a rule of thumb, try your best to avoid doing things exclusively to impress colleges.
