Hello,


You can surely do pgdm courses but he cant to do it in top colleges.Though he may get admission in average colleges where marks in not much considered for admission.

Good Luck

Dear aspirant, for CAT minimum 50% Marks are required in graduation level, but as your friend scored less than that, he is not eligible for the CAT exam which is a national level exam for the entrance in IIM. He might get admission in any private college where the percentage is acceptable and eligible in graduation  level.
Hope it helps.
All the best:)
