Can i take admission in IIT.i got b.tech 58% and i am mechanical engineering but i am preparing XE branch gate exam

Hello Mukesh. Yes,  you can write GATE with XE branch into order to get into IIT. You can get into M. Tech or Phd course with the XE branch in IIT. However, you cannot apply for psu with GATE score having XE as the branch. Moreover, every IITs also have their individual criterion for XE branch along with the GATE score. So before applying for GATE with XE, just go through those criterion in the respective sites of IITs.

Thus, even though you are a Mechanical Engineer, you can get into IIT with XE branch in GATE.

All the best.
