Can I remove disability from submitted UCAS application?

I have tried to use the ucas update form but it only allows you to change things such as passport, name, etc. I put social anxiety as my disability but I’m regretting it now especially because I’m applying for a few top unis, I want to remove it and I don’t really want any additional support for it anymore. Is it possible to just email UCAS and they will remove it?

You could contact the unis themselves to ask them to remove the flag, but it's not used for admissions purposes. If you do get an offer, you might get an email or two from support services but it'll all be voluntary as to whether you use them in any way.

It is not going to make any difference to you getting offers so dont worry about it.

oh ok, thank you!

Your chosen universities already have your application. If you call UCAS (0371 468 0 468) and if they are able to make this update, then they will to contact those universities to have them update their records too. That will potentially draw more attention to your anxiety.

Ironically, it is your anxiety which is causing you to want to remove this (accurate) information from your application. As @swanseajack1 says, it will not adversely impact your application - even for top unis.
