Is it nessecary to have a good GATE score to join NICMAR?

The institute does not accept GATE scores. Instead, it evaluates candidates based on a unique test, NCAT. For the final admission, NCAT score, academic performance, work experience, and Personal Interview (PI) are considered. 

NCAT is a test conducted online on Saturday and Sunday. There are three sections as discussed below.

After the test, there will be a group discussion in a group of 15 students. The PI will be technically based, but it will not be at a higher end.

After all rounds, based on the aggregate scores, the merit list is prepared. Overall, with a decent knowledge and scores in each round, you can get admission to NICMAR.
