Hey:)

Since you're from UP board, for PGGC you'll be counted in the outside-UT(general)pool, not the Chandigarh pool. In this pool, the cut-offs are always higher compared to home state candidates. With 49% marks, even for BA it's tough to get admission in the first round. However, your EWS quota can give some advantage 10% extra seats are there, but still the competition is strong. So, your chances are only if you try for less-demand BA subject combinations or in the later/vacant seat rounds.

It is safer to apply with EWS certificate and also keep other colleges as a backup

All the best!
