Hello aspirate 

Since this year the cutoff marks for Allahabad University is high as you haven't mentioned your category I'll consider it to be General. And so you have very less almost no chances of getting seat in AU for persuing bcom. Because the expected cutoff for UR this year is 185+ marks and so you may not get seat.

Good luck
