See you need to have such a combination in your class 10 such that you get the Physics, Chemistry and Mathematics in your 10+2 as it is needed if you want to study the BTech course.

I would recommend you that you must take Mathematics and Sciences of your 10th very sincerely as it will create a foundation stone laterwards.
