Hello

Both the subjects have a wide difference. If I will be honest with you, psychology even though an excellent subject does not provide a job option to most people in India. As far as BVoc is concerned, you can get a job in this faster if you are interested in what you are doing and have passion to make ideas work as it is a creative field compared to psychology which is about mugging up.

If I were you, I would analyse my strength and choose accordingly.

If you find it esaier to mug things up tha to create things then go with psychology, if you like creative work and inetracting with clients and having fun and hardwork then go with bvoc.
