Science

The B.Sc (CS) course mainly focuses on the mathematical and theoretical foundations of computing, rather than teaching specific technologies that may quickly become outdated. This course prepares you for higher education.
BCA is more professionally oriented; it prepares you for post-graduate or research work and also creates professional manpower for problem solving through application of computer science at the interface of business and technology.
If you want to join Indian Army after BCA, you should give CDS entrance exam as it is for officers post in army, you can join Army after clearing CDS.

Hello Jose,
B.Tech in computer science is a better option as compared to B.Sc course. B.Tech is a technical professional degree (engineering) which has good career prospects and it gets completed in 4 years as against the B.Sc (graduation degree in Science) which is a 3 year course. After doing a B.Sc to build a successful career, you will need to pursue post graduate studies in a subject of your choice since the B.Sc alone is not job oriented, unlike B.Tech which is a job oriented course.

You can do MBA in finance or can prepare for competitive exams to get a job in the banking sector.

Dear Anurag,
According to your statement, I would suggest you to firstly concentrate on your study. You can enjoy Bachelors life in every programme but that depends how you maintain your time table for fun and study.
Once you have knowledge and experience, you can earn well whether you are in medical, engineering, teaching or corporate job and enjoy your life too.
Pick the field according to your interest and caliber and give your 200% for that and than see the result.
All the best.
