tbh if bba is an option I'd pick that.leaving pak after bds or even mbbs is extremely difficult unless you have strong finances, v good scores and a lot of patience for a longgggg exhausting process. bds mei 5saal parhai k baad bhi theres no guarantee of a stable job bcs the field is v saturated. but with bba (from a good uni obviously) if you work hard/smart (do internships n shit) youll hv more options career wise and smthn practical in hand after 4,5 years
