which is better for b.tech gayan vihar university ya amity university?

hey dono hi bakwaas hain agar rajasthan mein join kerna hai toh VIT Jaipur ya JECRC Jaipur kero

As rightly pointed out by Piyush, I would say both are of no use. Look out for SKIT Jaipur. In case you wont make it, go for their sister institute VIT & VIT(E). If you fail there as well, look for VIT University.

look out for amity college of engineering noida..it is ranked higher than many other govt. and other pvt. universities
