Yes it is a good b school for pgdm but if your score is good you can get colleges much better tha dy patil 

like NL DALMIA 

SIES 

these colleges are better than dy patil but if your cut off is according to dy go for it or wait for next year to give entrance

Hey,

Dy patil is an average b school. It is not that good in all areas. The placements are just fine but not that great. Average package is around 2.8 lakhs per annum which is very low. I would suggest you to think of any other better college for pursuing mba.
