Hello Pooja, 

As the tentative merit lists for the Rajasthan belonging, out of Rajasthan and Kashmiri Migrants students have already been released by Rajasthan Technical University and there is not any kind of concept of Mock round with rtu. The nearest thing to that is tentative merit list which will give you an idea about seat allotment.

For Rajasthan students, the final seat allotment list was to be declared on 11/07/2019 but due to some technical issues, it was neither released on 11th nor on 12th of July.

The official site for all proceedings and lists is reapraj.com. You can refer to this site for further details. 

Hope it helped..
