See dude from my observation , if you do MBA from any small organization it hardly helps , it will surely improve on what you have at the moment but still MBA from a good college is preferable ! .
My friend got admission in a good college but her ultra orthodox parents wont allow her to stay in hostel !! . So she did MBA from a small local college , was getting 35k after her extc engg and now after MBA she works with 40 k after two years of hardwork ! . Sometimes I feel she represents pure hardwork but still the fact is no matter how hard you work , if you believe in on campus placement , you need to have a good college . Off campus is a different thing but more difficult compared to on campus placements . But considering you got no other option and you are not satisfied with the current degree , you go with whatever you have , get a decent job . And then in the job you have , somehow try to progress there . There would be your window of opportunity again .
