Give short, noncommittal answers to any questions they ask. For example, say you’re busy working on school work, or simply reply “yes” or “no.”
Join a sports team, get involved in school clubs, or volunteer in your community. You'll get space from your parents and gain experiences worth noting on college applications.
Consider getting an after-school job. The time away from home will give you space and independence from your parents and help you to earn your own money.
