Hiii

This is difficult to say what marks you must score because every year, cutoffs keepon changing depending on different factors. But all we can say is tha there is  high cutoffs, and competition is tooo high so it is suggested that you try to keep a high target atleast around 570 marks and above to secure a semigovernment seat in DMC ludhiana.
Rest you can refer to previous year cutoffs, to get to know the trends.

Hope this helps
Thanks!!
