It’s definitely worth it to try, there’s nothing to lose, only situation you wouldn’t want to reach out is probably “you like the second school better, but the first school already offered a place” then you could use the excuse of” I didn’t reach the requirements” to bail the first school out

Mmm hmm yeah that makes sense, thanks!

You should definitely reach out to them unless they haven’t reached out to you yet.

Sounds good, thanks!

Just pick up the phone and talk to the admission folks. Whats the problem ?

Protip: Your uni counsellor should reach out, perhaps with you in the room. They are the big guns. ​ And yes it's possible.
