Is it compalsary to take addmission in the couching classes providd by the institute or we may refers to other?

It is your wish which institute you want to choose for tutorials. If you think it is necessary then you should join or else prepare yourself.
However, if the institute refers a coaching class then it might be that they have a tie up and the classes are done in synchronization with the course materials of the institute.
But, it is not mandatory.
