Zain,
Why you taking tension brother ? You are still in process.
It doesnt really matter if its PPR1,2,3,4,5 it varies from person to person's file.
I faced same delays, but i was asked everything in one email.
1. Updated forms (you dont need to attest it)
2. RPRF
3. Police clearance Certificate
4. Re medicals
5. Height, eye color and passport # and expiration
and yes i was part of QA process and when i ordered gcms notes it said completed-QA
degree was issue, but it was resolved under special condition of 2+2 by the case officer after review during QA process
just matter of time brother , insha Allah everyone will be through.
cheers and be hopeful.
Regards
Ahmed.
