Dual

MCA is not a good option. Many colleges and universities are discontinuing this course. Thus is because three years you will study everything in computer field but no specialisation. in other words MCA students are not employable.
you can very well do. one year specialisation masters in UK which will get you a job immediately.

There is no difference as per Governing body Norms.
If you wish to appear for entrance test for admission in masters integrated is not a good choice.
But if you want to continue from same institution without a gap integrated is better as it may save your time and money.

Hey Saurabh,
Here you should specify that in which course or field you are interested to do a 5 year integrated program. Assuming that you are interested in engineering than you can opt for either B.Tech-MBA or B.Tech-M.Tech. Both the programs save your one year as well as give you the whole study in a single shot. Number of students going for integrated programs has increased significantly over the past few years. Suggesting some universities offering integrated programs.

Hi. Last year Jk business School has 100% placement record and is awarded with "Best Management college for placement in 2016. Right now internship interviews are going on and college is doing a great job in this too.
Yes JKBS offers dual specialisation.

Hey Laxmi Kant,
Yes definitely you can go for integrated BBA-MBA after 12 and here you save your one year too. Integrated courses are quiet popular nowadays. Suggesting you some good colleges to go for -
