Can i give 2 entrance exams in same year???

no

Yes you can try even more than two, actually the thing is different privately run colleges and universities of good reputation conduct their own tests to let students get admission, along with a national level test you can try at as many places as you can, so, go for it, i may suggest to try at – Pragati Engg College, Kakinada,...........Lovely Professional Uni, Phagwara,.............Mody Uni of Sci and Tech, Sikar,.........BHu, Varanasi
