To get admission into B.tech, you can either give JEE or UPSEEE, after which you can directly go to the college and take admission. You can also get direct admission if you have scored more then 55% of aggregate in science stream, (specifically, PCM and PCM or PCB for Bio-Tech).
There no mandatory entrance exam.
I have 70 percent in my 12th so I'm eligible for admission But I gave UPSEE examination and cleared it. Then UPSEE counselling. Overall best faculty.
