in the first stage you will have to acquire knowledge of 11 and 12 in commerce stream ,you will be asked questions on the basis of your past classes i.e, 11 and 12.
in the second stage your working level experience will be checked ,
in the third stage your working quality matters ,you should be smart worker instead of hard worker, along with this you also need to have coaching for this stage.
