For the UG program, the admission is based on KVPY, JEE (Main), JEE (Advanced) and AIPMT. For the PG M.E. program, the admission is based on GATE. For the Ph.D/M.Sc (Engg) program, it is based purely on marks obtained in the research interview.
For the UG program, the first round of offers were made based on KVPY and the first counselling was held on May 30. The other round of offers will be made in the next few weeks. The second round of counselling will be held on July 4. The cutoffs for the UG program will be similar, if not higher, compared to last year.
The offers for the research program will be sent on 12 June. The offered students will be given around 10 days time to pay the fees. The waiting list will be operated subsequently depending on the numbers who do not pay the fees.
