In today’s sinerio and demand BCA+MCA is better than only having BCA as,because the main advantage is you save one year after. MCA there is huge opportunity in IT sector and MCA is must for every student persuing BCA to get good carrier ahead .on the other after completing BCA you must go for MCA from a top institute to get a better placement and good salary because off campus there is no place for BCA MCA’s as there are huge number of b.tech’s are there already in demand for IT sector
so….my opinion in brief is if your are getting BCA+MCA from top college then its good only BCA is like having a diploma so go for bca mca integrated program …best of luck
