BCA

BBA stands for Bachelor of Business Administration and BCA stands for Bachelor of Computer Applications. Both these courses are Graduation level courses. The duration of both the courses is 3 years.
BCA course is technically oriented with a variety of computer-related subjects or technical subjects that the candidate is going to study. He is going to have a good number of job opportunities in various IT companies soon after the completion of BCA course.
BBA involves a variety of subjects which are related to business and is management-oriented. These people can have job opportunities in all the business sectors.
My sincere suggestion is don't look for job opportunities soon after the completion of your Graduation whether it is BBA or BCA because you will not be paid much if you join with graduation as the highest academic qualification. In addition to this, the workload will be more. In some companies, hard-core working activities will be allotted to these new joinees who join soon after the completion of their graduation.
I suggest you to choose the stream which you are interested in between BBA and BCA. And try to get admission for the respective course in a good college. If you join BCA, then go for the MCA course later. In contrast to this, if you join BBA, then go for MBA course and try for job opportunities on the basis of post-graduation as the highest level of academic qualification.
Have a good preparation for the respective entrance exams which will give admission for post graduation courses from the first year of your graduation.
Wish you all the best.
