See, I understand your pain but you have already completed 11 th standard. What do you think ? Are you able to cope with the studies ?
You should have gently told your parents that I am not going to take science in any damn situation. But now you studied for one year, so how’s that for you ?
Now if you revolt you’ll be forced to start again from the scartch. Think again wisely & let me tell you that you can pursue higher studies in humanities even after science stream easily.
Being in science also opens up a wide variety of career opportunities for you. So think about it. Studies are never bad but I understand you can’t expect a shark to fly. Yet try to see taking science as opportunity for you & have faith it can move mountains.
But I am being practical here, had you said this thing one year ago I would have asked you to declare non-cooperation movement against your parents. But now the situation has changed. You have adjusted yourself in your stream & leaving it will be a overall a tough choice.
Finally it’s your call & hence so do the needful very rigorously !
All the best 👍
