Like a language or a sport?
Yes. Try to take 4 years of the same language and get into varsity sports to have the best chance. Other extracurriculars and community service will also help.
Welcome! I couldn't find anything for Juliard but here is what I found for Yale. Info is from naviance the college prep site my school uses.
There are a few schools under Yale so I looked it up for the standard university. Here is what I found. These factors are what has the most weight for them.
Character/Personal Qualities
Class Rank
Curriculum Rigor/School Record
Extracurricular Activities
Recommendations
Talent/Ability/Competency
Aside from these Yale has not explicitly stated that they recommend 3 years of a foreign language or sport. But it can be implied from their focus on your course rigor and school record. In general selective schools will like to see you have one more credit per subject of what is required. For example instead of 3 math credits 4.
