Hello Aspirant

I think there are plenty of options related to science stream and also many vocational subjects that don't need you to be of any particular stream for instance LAW, interior designing,  fashion designing, textile design,  graphic design, bachelors in any of the foreign languages and many more.

You should choose a creer that is best for you, that intrigues you the most!

I'm attaching a link for career options after 12th class with science:

Hope this helps you !

All the best!
