Hi. 

The ultimate goal of any aspirant is to get a good ROI at the end of the PGDM course. Today, there are lots of mediocre colleges offering PGDM/MBA which doesn't have a good course or good placement.

I would suggest you to prepare well for next year and give your best. Do not depend on just CAT for your MBA college. Try CMAT, SNAP and NMAT too. They are easier to crack compared to CAT. 

ALL THE BEST!
