Hello aspirant. As you mentioned that your rank is 12522 in ts eamcet under OC category, it is very difficult to get admission in Vardhaman College of Engineering, Mahathama Gandhi Institute of Technology(MGIT),Gokaraju Rangaraju Institite of Technology (GRRR) and GNTW. Your rank is too high when compared to previous year cutoff ranks. It is impossible for you to get admission in the above mentioned colleges. So better try for another colleges.
