Thanks everyone..
I applied on 24th June from Pune under Non-SPP and the file got processed at Bangalore center. I got the confirmation exactly on 15th Day, coincidentally I called them yesterday and they said usually study permits take 15 working days and since its my 15th day they asked me to wait for 2 more days and see. However, I got the approval mail by evening and the passport dispatched mail in couple of hours after that.
Waiting to collect my passport tomorrow.
