Around 455 marks was the cutoff in 2017 in Dr. Harvansh Singh Judge Dental College. It was equivalent to an ALL INDIA QUOTA rank of 41730 approximately. In 2017, the cutoff was 467 marks. Considering that you have a ut QUOTA, I will recommend you to target around 450-460+ only since the cutoff might vary this year as all the other exams AIIMS JIPMER etc have been scrapped and NEET is only going to be a common base for all the entrance into different midcal courses.

Refer to the siter below to know the cutoffs of your colege and also the othr available colleges of Punjab -
