Your test scores and grades are very solid, same with your ECs. I think your chance of admission is pretty high. Regarding your concern with ED - last year Rice’s ED admissions rate was 20% v. RD 15%, which isn’t as significant as some schools but still a statistical advantage. If you’re not completely sure about financial aid, I would say maybe apply EA somewhere and then apply to Rice RD so you get a chance to assess all your finaid offers.
