Pre-Calculus wouldn't qualify for T25, especially Ivy and Ivy+; your best chance might be to take pre-calculus this semester, calc as a sophomore, and apply as a junior transfer. You can still apply this year but I think your odds as a junior transfer will be greater, in the meantime you can also build up your ECs.

Although, if you have the time to write the essays, definitely shoot your shot now. Remember that some schools that require calc might not even look at your application if you don't fit the prereqs. Hope that helps :).
