Hello,

Chosing an optional subject with the main stream is an important decision and I believe it should not be solely depend on the basis of marks. Like, what your goals are in the future it should support that particular objective as well. There are many options Available to choose from and you should accordingly make the decision. From the past records, it can be seen that Physical Education is considered to be the best option to score and get good marks in the board examination but if you have interest in like Entrepreneurship you can also opt for that and get good marks. If your purpose is only marks then I think Physical Education (Phe) will do the work.
