Easiest route to get to IIM Calcutta?

Looking for a route to reach IIM Calcutta

I live on the Blue Line , is changing metros possible? I was looking at possible changes from Kalighat to Majherhat to get to Joka or is there a station I'm missing?

Another possible route is from Netaji Metro station but idk if there are any buses or anything that go in that direction

Suggestions for any buses or anything from any metro station would be appreciated too!
