As you have not mentioned  your preferred courses and the cutoff are different for different courses but they are mostly the highest for CS or  IT departments so I am assuming that  you want  seat in CS OR IT Department so if we look at the cutoffs for year 2019, cutoff Rank by rank (4th round) for CSE in this college was 38,614 and the same for IT was 44,629. So according to the previous trends of the cutoff for these two branches in this college, you have a high chance of getting into this college with your preferred branch.
