Hello Ayushi,

Since your friend has achieved 49 marks in the gate examinations, you have a good chance to get admission in the IIT's, and what course or subject you wish to study also plays a vital role, but as u mentioned in OBC category, you still might get a good chance.

For example, the top branches would not be available but if IIT is the target then your friend has a pretty good chance.

and for further details, you can even visit our website, where there is a detailed description of all the major courses offered by the IIT's and which one would be the best for you.
