If I were to reapply to a college (as a transfer) I was accepted to my first year, can I reuse my college essay that got me into the school? Or not?
You need to write all new essays.
But first ask them what you need to do. Sometimes it is possible to just reactivate or reopen the app, and not much new is needed.
Call them first and see what you need to do.
I’d write new essays for sure though.
