Well, legally you can, but most selective private colleges aren’t going to say “oops we made a mistake last year” and admit you.
This doesn’t apply to community college → flagship if you spend 2years at the CC, since you’re considered& admitted/denied on the strength of your CC record.
It’s also different at large public universities and sometimes at universities where you ended up on the waitlist and expressed interest till the end.
However overall a good strategy is to create an entirely new list. You may keep 1-3 in of you previous year’s reaches but only as add ons since the odds are so poor.
