I'm from andhrapradesh ,I want to pursue my pg in gen med from Delhi University , won't language be a problem for me
See every year from different states, different student come to study at DU from different states. So with they also accommodate. As a result, if you get a chance there then I would recommend you to go for it. Initially you may find linguistic challenges but within a month or two you will get a ease there. So you may have to face some problems linguistically to communicate with peoples but academically you will not face any problem.
I hope this answer helps. All the very best for your future endeavors!
