Who is clearing available for?

If I accept an offer for my university, and make them my firm choice. Do I still have the option to go into clearing at around results day? (if I change my mind or want something different)

You do have that option, yes. However, you can't enter Clearing whilst you hold an existing offer or place. So you'd have to select the "decline my place" option in UCAS Hub to drop into Clearing.

That's obviously risky, as you then might not secure the place via Clearing which you were hoping for. That would leave you without a place, and having to search for alternatives via Clearing.

Thank you for your reply.

What about if you’re just simply exploring your clearing options? As in, going to university websites/ calling them about potential places for your desired course? If and after they accept your offer to go into clearing for your desired course at their university, would it be possible to then, after being accepted to the other university, to “decline my offer” for the choice I picked previously?

or is this entire situation not possible since I didn’t “decline my offer” beforehand?
