Akash, first of all, you haven't mentioned the name of the government college in which you want to take admission. Second thing is irrespective of the fact that an MBA college is government or private almost every college has a procedure to give admission to students which starts with one of the MBA exam marks like CAT, XAT, CMAT, MAT, CET, SNAP, NMAT etc. Among which CAT is the most popular MBA exam and the maximum of the colleges accepts CAT exam marks for admission. So, after clearing MBA exam you will need to go through the second round process of GD, WAT and interview and then you can get a seat in a good college to pursue your MBA degree.

Feel free to ask if you have any more queries. All the best!!
