Does anyone know anything about getting into an Indian university? The career guidance people in my college don't know anything. I've written to the Irish Embassy in New Delhi and the Indian Embassy in Dublin but am still waiting to hear back.
I have an undergraduate degree and now want to go on and do a masters. I'm going traveling for at least a year first so I have time to plan this.
I saw on the University of Delhi website that a few of the courses are for Indian nationals only. I could understand if this is the case, it seem there's a massive demand for places so why give them to the foreigners.
The University I want to go to is the University of Calcutta. I've emailed a few people but no luck yet.
Thanks.
