Believe me ! For doing Mtech, you can straight away do MBA in power. Because the Mtech course is designed in such a way that even they dont have any idea about any kind of energy.
Only Mr.Bansal who is a Mtech dean knows something about energy efficiency. Remaining, crap subjects and staffs are not proficient enough to take solar, hydro, green buildings, biomass, but the college has a good name. so you may get placed in some company (not sure).
P.S: I am one of those who studied this shitty course, last before year. Almost all the subjects are there, related to energy, theory part is no way related to working. So, i suggest you to take MBA or study in any foreign university unless you have financial problem
