Hi
There's nothing lyk girls cannot do mechanical engineering , they do equally good as boys in mechanical or civil engineering. NIT Surat is a much better choice than HBTI Kanpur, and is a good decision. NIT Surat is one of the top NITs in India and has gt good faculty and infrastructure.
U can see the placement rankings from this link engineering4edu.wordpress.com/2009/06/27/top-indian-engineering-schools-ranked-by-placement-record/  . NIT Surat is way up HBTI Kanpur in overall rankings too , so it wud be a better option.
						

							
Hi
NIT Surat mechanical engineering is good. Doing a B.Tech Degree from a reputed college adds to ur resume more than doing a better branch from any college. ECE is although the favorites among the topper students in top institutes bt comparing HBTI and NIT Surat, one is bound to say that NIT Surat is a much better place to study.
You can see the placement statistics for nit surat from the following link www.svnit.ac.in/tnp/pastyears.pdf  .
one can still think about comparing ECE in HBTI to Mech in Surat , but comparing mech in both the colleges then NIT Surat has to be the first choice.
