you can do your degree but legally you cant use both degrees at same time...
but most of the time you need not to use both of the degrees simultaneously...
one more thing is you can get 1st division easily but it is difficult to grab 1st division from p.u...
so, its better to do another m.a from uos and use any of them accordingly..
suppose you are applying for lectureship in ppsc you can apply for both showing one of respective degree without disclosing second one...
