Hello there. It's been a opinion for many that MDU Rohtak is having a violent environment and their are problem that are being created by the mischief substances but the reality is little bit different. MDU Rohtak has a very friendly environment and the unity among the students is on a whole different level. Every one lives with brotherhood and have respect for each other. 

I am not saying it just in air, but it's the truth as I am resident of Rohtak and my home is just 2km from University. So if you are a focused student and do not get involved in any sort of problem then it could prove to be a good option for you. And also another thing it's not like that it's Rohtak so their is Jat samaj only. Many community lives together with a very healthy relationship and thier is no such thing like dominance of a single community. 

But on one end their are always some misleading component who make the whole society spoiled. So if you are able to make a distance with them, you can easily live a better life and focus on your future.
