Hello Vinit KUmar !

Firstly i wanna tell you that all these private colleges are same.But there is some poiints on the basis of that we can filter one of them.

Like your home town.If you are basically from jaipur only Theen JECRC is the best option.

I also wanna make this clear for you that JECRC  is best among these all college(Arya, SKIT, JEC, Poornima...etc.)

At JECRC you will experiance a college like enviroment, and  at all other place they have lots of Boundations on their day to day life.

Also you get Good technical Exposure then Udaipur in Jaipur.

If you  are a tecnical Keeda  type person then go jaipur otherwise all are same.

Hope it helps yu.
