Hi,

Selecting a specialization depends on your intrested, aptitude and ability to handle that subject.

If you are not confirm which specialization will be preferable to you, I would advice you to compare the syllabus of the courses. Though it does not give a detailed idea of what you will be studing in the course it will help you to understand the nature of the course superficially.

For example if you compare syllabus of marketing and buisness analytic you will find that in marketing you will be going to study the theories,concept and stuff related to marketing. And in buisness analytics you will be studying with companies data, its analysis etc. So if you are good at mathematics or with number or statistics you may like buisness analytics branch and if you are intrested in marketing, management type work you may like management brach.

Hope the above approach helps you in deciding the right specialization.
