Hey there,

Assuming that you are in 11th standard, i believe that you should repeat 11th class as if you are not intrested in science then you shuold simply leave it. It's of no use as you don't have intrest in it.

You should choose your stream wisely as it is the base of your career and a strong base will lead to a more stronger foundation.

Just go for your intrested stream and follow up your passion. I assure you will come up with flying colors.

All the Best.
