Hello Rakesh,
If your sister cannot cope up with Science, then let her choose the stream of her choice. If she wants to pursue career in banking or accounting, she can join commerce. If she is interested in something in arts, then let her join arts. It's all on what she wants to do in the future. You will have to take a leaving certificate from the school and they will give back the original documents of class 10th. If they do not give, you can request the principal for the same.
