Hi Sadi,

The cancelled checkbook is for letting the csab know the bank details to which the fee will be refunded if the candidate isn't able to get a seat/withdraws from the registration. Therefore it is mandatory to get a cancelled check available. Please contact the bank in which you have an account and get a checkbook as soon as possible. Because you have to pay in csab just after registration. And this process won't be extended after 27 July, 5 PM. So hurry up.

Thanks.
