Appeal Question

I have been denied today during the afternoon and now appealing to CPP.
It asks for Documentation to support your appeal (e.g., transcripts, SAT/ACT scores, proof of mailing submission of requestion information etc,)
I have submitted everything on the requested information and would like to know to prove that ( financial aid stuff)
Also have taken the ELM/EPT test and would like to know how to confirm that also.
