It depends on college through which you want to pursue your course.

I am giving you an example of The University of Burdwan  curriculum:-

1. You will be tested in following ways:-

(1)Theory  ,  (2)Activity and (3)Teaching Ability.

You will be tested once a year in theory. While in other two , it will be tested from time to time.

To pass in theory , you need atleast 30%

To pass in activity and teaching skills , you need atleast 40% .

And one more thing! 80% attendance is also a necessity!!

Best of luck!!!
