Hello Sara!
It's tough. If we practically look at your situation then in 6 months when you have no clear concepts of 11th-12th then it is really tough. Since you are from West Bengal, if you have ST category and you score around 200 marks then it is possible otherwise it seems very much tough.
Hope that helps!
