B.Sc

Hi Praveen,
IT (Information Technology) is a growing field, in India, and is looked upon, as one of the industries to provide jobs. A science student, interested in joining the IT bandwagon is usually confused between many courses on offer at the undergraduate level and might end up joining a course which might not be as beneficial as some other course.
One such confusion comes between choosing BCA (Bachelor of Computer Applications) or B.SC (Computer Science). We have listed some of the difference in these courses to help you reach a decision.
B.Sc (Computer 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and theoretical foundations of computing, rather than teaching specific technologies that may quickly become outdated. The course prepares you for higher education.
It is more of an academic course and admission to most universities is based on your performance at the HSC level. Having physics, chemistry and maths is essential to apply for this course. Education after B.Sc: You can pursue courses like M.Sc or MCA. You can even pursue an M.Tech, after you complete your M.Sc, if the M.Sc(CS) degree is recognised by UGC or AIU (Association of Indian Universities). For M.Tech you can appear for the GATE examination conducted by the IITs or check individual universities which conduct their own entrance exam.
BCA - This is an undergraduate program where students are introduced to various areas of computer science, programming, database design, software engineering, networks and information systems. This course prepares graduates for further postgraduate research degrees or employment in any variety of roles in organizations that require expert professionals who can apply computer science principles to solve problems produced by the interface between business and technology. It is more of a professional course. The admission to most colleges is based on an entrance test, the eligibility for most is 50% or above in HSC with Maths as a compulsory subject.
You can go for an MCA or you can directly apply for an M.Tech, after you complete your BCA.
You can not pursue an M.Tech directly after completing your B.Sc , You can pursue an M.Tech degree after you complete your BCA.
Hope this helps.
Wish you luck.
