Hello sir,

Thanks for reaching out!

I'd recommend not rushing to change her stream before fully understanding the situation. A failed unit test is not uncommon in class 11 since it's a period of academic transition where many students need time to adjust. struggling in unit test doesn't define her capability.Instead of switching stream immediately, talk to your daughter and try to understand her interests.If she truly like science but didn't perform well this time and she believes that she has the potential to grow, That's okay she may just need a better guidance, a tutor or a new study routine.With support and effort she can catch up and grow.but If her heart is'nt in science and she feels more connected to another stream then its wise to consider a change .

The goal is to help her learn in a space where she feels confident,capable and inspired.

Better guidance for clarity:
