Hi Aspirant,

Choice of stream depends completely on your field of interest.If you are interested solely in software side then you can go for CST as the course deals with software part and other such codings.Both CSE and CST are good course in their own aspects.There is as such no difference between these two course as both prepares you in technological field.

Hope it helps!!

Obviously! You can. Interest is the most important thing which will drive you to different level of prosperity. So if you are interested about the subject then you should go for it.

I hope my answer helps. All the very best for your future endeavors!
