Admission to Mumbai University colleges or St. Xavier’s through BBA is possible, but it depends mainly on your Class 12 marks and the cut-off list. Mumbai University–affiliated colleges usually give admission based on merit, and some colleges may also conduct an entrance test. St. Xavier’s follows a stricter process, where students must clear the entrance test and interview along with meeting a high cut-off. Simply applying does not guarantee admission. Your chances improve only if your board marks are strong and you prepare well for the entrance process. It is always better to apply to multiple colleges and keep backup options instead of depending on one institution alone.
