Yes, MBA after BBA is one the best course to make a brighter future. It opens ample number of opportunities worldwide. You should look for some good college which offers dual specialisation in MBA. Dual specialisation was not so common a few years ago, but the trend changed. Not all but few colleges in India offer dual specialisation in MBA. Quantum University Roorkee located in Uttarakhand is one such college where dual specialisation is offered. The market needed people with versatility and more and more domains were merged in the dual specialisation. It may very well be that one of them is major and the other is minor or they may be of equal weight. But in most dual specialisation MBA courses, both carry equal weight with a full curriculum for each being taught. Fee is quite affordable here. Placements are really good as more than 100 international companies visit each year. The best thing about Quantum is that an assured Placement with a minimum CTC package of Rs 4.00 Lacs per annum* at the time of passing out or within six months of passing out !
A cash-back equivalent to the difference between 4.00 Lacs and the actual placement package in an unlikely possibility of getting placed below the assured package. For e. g. , if a student gets a CTC of Rs 3.50 Lacs per annum, then a cash back of Rs 50,000 shall be made to the student.
