Nothing wrong with being a 16 going on 17 year old and being a freshman on campus at a flagship U (globally gifted son did that for UW-Madison). It is good to also have a well rounded education to prepare yourself for a good college and life. Music, arts and more social studies and humanities as well as math/sciences. A foreign language. Sports/athletic time. Be sure to educate yourself in more than just STEM interests. Being home schooled and in a metro area allows you time to accomplish as much of these as a student exposed to a regular HS experience.
