Hey!

Firstly note that both are the off campus colleges of delhi university , so they are more or less the same . Bit the difference lies in placements and societies , as in both these things , JDMC is far better than Kalindi. But JDMC lacks behind kalindi college in faculty. So , it depends upon you which are the most preferable  things for you before choosing a college.

I would suggest you to go for JDMC .

Also note that no matter which college you choose , in the end you are going to get the same marksheet from both the colleges issued by university of delhi.

Hope it helps!
