College is so much more than taking classes. Going for a PhD requires research and contact with professors, which online programs won't provide.
You're better off finding a good LAC where undergraduates can do research or an honors program at a Brick and mortar university.
What are your stats?
(Some Universities, like Amherst or Hamilton, don't have requirements, but expect stellar applications.)
Apply test optional to Denison (and Bates)?
No, top LACs don't "look past" SAT scores - they look at everything, if you have strong course rigor, essays, recommendations, EC's, etc.
Is the 3.66 weighted or unweighted?
Have you run the NPC on all of these and brought the results to your parents? Can they afford net costs off income and savings?
Your list is very reach-heavy (Baylor, SMU, Richmond, Kenyon, Bates) and you only have one safety (Ithaca). Denison test optional is a good match as well as Elon and Trinity. I'd add one more safety and one more match.
^not necessarily, as 80 is a pretty good score for most colleges.
(79-85 means readiness to attend a US college, 61-75 indicates community college instruction is more recommended.)
100 means more than the ability to do well with college coursework, it means the ability to handle the very fast pace and high expectations of top US colleges.
I wish native speakers currently in HS could take the test; beside Listening, which all would do well in, I wonder how they'd do. It's not an easy test, by far.
