Hello Hema

This Year's cutoff's has not been released yet and if you consider last Year cutoff's then for General it was 37.1, for OBC it was something 34 or 33 and for SC/ST it was 24.7. 

As many are saying that this Year's question was bit easy hence cutoff can be little bit higher than the previous Year.

To Get into IIT you must have a GATE marks of above 50-55 (to get Shorlisted) as your stream has not that much competetion as compare to mech or ECE or Civil or EE.

To get into PSU (to get shortlisted) anyrhing under 1000 AIR will be fine.

Hey Hema.

See since ur discipline is not the core one in the field of engineering thats why the cut off u r getting for the qualification is : 37.1 for general

                              33.3for OBC as per the previous year records.

But these marks are juust for the qualification. For ur further studies in the discipline u have chosen u must be getting a score of more than 650 for ur admision in IIT DELHI if u r from general quota and 600 for OBC. this score is given per thousand and the cut off is given per hundred.

About getting PSUs ur rank must be below 500 to get some good jobs for ur work experience and that includes ur marks above 700.

ope this helped u. Ask if u r having any query.

Good Luck
