Hi

Reporting Centre can be any of the NITs, IITs, GFTIs. In case of IIEST Shibpur, the reporting centre can be IIEST Shibpur itself, or NIT Durgapur, or any other NIT or GFTI in your respective residential State. You can either report at IIEST Shibpur or any other NIT, GFTI. All the colleges mentioned in JoSAA for choice filling, are all valid as reporting centres.

Best of Luck.

Hope this helps.

Cheers!
