The cutoff varies year to year with number of candidates appearing in the entrance examination and toughness level of the exam. 

I took the exam in 2016 and as per the past trends, a general rank within 1300 can get you admission in this University. For getting the desired branch for a General Candidate having no reservation, you have to be within 500, especially for Mechanical and CSE branches. 

If the paper is easy, the cutoff can be as high as 400/600. But in previous years, 270-300 marks out of  600 can get you the desired branch. 

For a General candidate, the eligibility criteria is at least 55% marks in 10+2 and a minimum average of 60% in PCM without grace. 

Hope this helped. All the best.
