Should I take CSE in UIET CSJM Kanpur or drop?

You should choose the branch as per your choice and interest. It would be advised to not choose CSE just because it is the highest-paid.

Secondly, if you are pursuing CSE, you will need a laptop with a good internet connection. You cannot always be dependent on labs. You can also join online courses offered by CODING BLOCK, CODING NINJAS, EDx, MIT, and many other MOOCs to get good at programming.

It is not necessary to always look for a brand tag if you really believe in yourself especially when you are studying CSE. Placement opportunities are available in reputed companies such as Google, Amazon, and many more by your skills in the definite field.
