Fellow student here. The one unfortunate part of the college process is basically needing to be at your best by sophomore/junior year of high school to have a shot, so I understand your desire to get that opportunity back. I know your question is about the possibility of transfer and not the odds, but I think this is a question you might benefit from raising with the admissions staff at whatever HYPS school you’re trying to get into. Ask about your eligibility and maybe even figure out what you can do to better your shot. Best of luck
