No it is not possible

No-one can predict the actual WBJEE exam cut-off of any college including Aliah University, Kolkata. Every year the cutoff of Aliah University changes as the exam will be evaluated on many factors which are relative and depends on many parameters. Some of the factors are mentioned Below:

• Number of Candidates applied for the admission in Aliah University
• No of candidates passed the exam
• The difficulty level of question paper
• No. of vacancy for this exam
• Cutoff may also be sectional wise

So you will need to wait and go through the counselling procedure. Still with your GMR rank 15166 and the OBC rank 749 you have a decent chance to get admission.

Feel free to ask if you have any more queries. All the best!!
