CUSAT is one of the underrated colleges in India, especially in Kerala. It is at present the second best engineering college in kerala. Perhaps, college of Engineering,  Trivandrum can match cusat. Nit Calicut is unrivalled for first. The facilities, exposures and quality of facilities you would get at Cusat is excellent. The value of Certificate from Cusat is immense even outside india.
You won't be disappointed.
Good luck...
