No. From the UCF Undergraduate Admissions webpage:
“You can apply up to one year prior to the term for which you plan to enroll. Freshmen should apply between September and December of their senior year in high school.”
UCF uses rolling admissions, rather than a specific “decision day” like some schools. It costs $30 to apply. Once you get your acceptance, you have the option of committing by paying the $200 enrollment deposit, or waiting.
If you choose to wait, your spot is still held until a deadline (don’t remember when that is). If UCF is your #1 choice, it makes sense to commit early and apply for dorms and wrap everything up.
If it’s a “safe school” for you, you can wait but if you wait too long you risk getting shut out of the dorms.
There is an amazing wealth of info on all subjects on the UCF website, so you should really explore there. Also, just FYI, if you can’t find something, their website has the best search feature I’ve ever seen on any website.
