Please don't start a new thread each time you post. Stick to one thread, as it helps to have all the information about your case is in one place. - Thanks.
If the only reason for refusal is oversubscription, then the sort of arguments you need are here:

- and this is what your case should focus on. As tiredmum says, general academic evidence is unlikely to be relevant if the only issue is oversubscription.
There is a bit of advice about setting out an oversubscription appeal here:
I usually suggest one of two things:
1. Send in a detailed written statement with any supporting evidence, and then at the appeal just remind the panel briefly of the main points, or
2. Send in a brief summary of the main points with any supporting evidence, and then go into more detail at the hearing.
You can, of course, send in a detailed written statement, and
go through all of it word for word at the hearing. If it's very lengthy, though, it may make the panel feel rather weary, and may not be the best way of winning friends and influencing people!
