Considering the opportunities which may get available for you in the future, I would suggest you go for Chemical Engineering at NIT Surat as it would be a better option over metallurgy. As my sister studied there, I am very well aware of the college and its pros and cons.

• Many PSUs and organizations recruit students of the Chemical Engineering department from NIT Surat.
• Some of these PSUs which recruit from the college include BPCL, HPCL, IOCL, and COAL India.
• Many people consider NIT Surathkal to be better than NIT Surat based on incomplete information and the NIRF ranking released by the Ministry of Education, India.

Choose wisely after performing a significant amount of research and analysis about the courses that you wish to get enrolled in from either of these institutions.
