Hello,

Diploma is the Course done after completing the 10 standard.

All the branches are good, you have to know that which branch will suits you and in which stream you are interested if you are interested in the software field you can choose the CSE ( computer science engineering) or IT ( Information technology) , if you are interested in the mechanical you can choose the mechanical, if you are interested in the stuff like circuits and electronics and the communication stream you can opt ECE ( electronic and communication engineering) , if you are interested in the machines you can opt the EEE ( electronics and electrical engineering).

Everyone has their own interest on the particular stream if you are interested in any of the above streams you can happily opt any one of them.

Thank You.

Hello.
All branches not only in diploma but also for Btech are good and best there is a good career scope in all these branches but it depends on a people which branch you Adopt, that is you need to see that where your passion is, if you are a skilled person in any branch then definitely it will be better for you, always go with that branch where you feel that you are enjoying the subjects and you are finding that the consistency is maintained ,
Best of luck.
