Hello,

From your question I see that you have a confusion between these courses. Some of them are UG courses and some are PG.

UG: Bachelor of Technology (B.Tech)

PG: Master of Computer Applications (MCA) , Master of Business Administration (MBA), Master of Science (MSc)

you need to do a UG course before you go for a PG, So out of the ones you have mentioned you need to do a B.Tech degree and then go for highers based on your preference

Thankyou
