Just like the NCERT Book, in Serial Order Wise, the chapter is divided into exercises and examples. This is useful if you are looking for answer to a specific question.


That is not a good way of studying.

In the NCERT Book, first question is of some topic, second question is of some other topic. There is no order

We have solved that using Concept Wise.

In Concept Wise, the chapter is divided into concepts. First the concept is taught. Then the questions of that concept is answered, from easy to difficult.
