Cutoffs for every college change every year. Last year closing ranks for JEE MAIN are 50k for general category , considering your homestate quota and UR category(as you haven't mentioned your category) , the cutoffs are not likely to see such a major drop from 50k to 115 k this year. So, sorry to say but you seem to have no chances of getting a seat in CSE branch.

Don't lose hopes as you can still get a CSE seat in some other colleges. To predict the list of colleges where you can get a seat  , you can use JEE MAINS college predictor tool:
