1st refusal was due to missing transcript. I don't know who told you it is not mandatory, but it is 100% required. You should ask your agent to send webform to enquire about status. Not all applications will be processed in 20 days, many people have had longer delays. You also have attached a lot of unnecessary documents like CA certificate, marriage certificate, 10th & 12th mark sheets. You have to wait for decision.
got 2nd refusal Based on my purpose of visit.
Applied for GCMS report on 15th Aug. Requested Univ for Deferral.
What else can u suggest I add or attach this time??

Wait for CAIPS and see why exactly they refused. Then make a reply based on that and attach in SOP
