Hi Aishwarya, 

Based on previous years' results, DSM DTU's 2019 cutoff can be expected to be around 80 + percentile, however these are just my speculation so kindly consider it likewise. Sine cutoffs are very relative, they change by a margin every year, whether an increase or a decrease, also because they are based on a number of factors such as the number of seats available, difficulty level of the exam, number of candidates sittinf gor the exam etc. 

Therefore, I advice you to kindly just wait for the cutoff as and when they are out. I hopw this was helpful, all the very best!
