Hi Iram

You apply in whichever university you want but at the same time you must fulfill the eligibiity criteria of particular university .You can appear for the entrance as well but you can't take admission in more than one .Now-a -days because of aadhar system you can't do such things which was possible few years back.

So if you wish to appear in entrance of more than one university go for it and analyse yourself and at last choose one to take admission.

Good luck
