So many rules and laws in idt

Hi All,

I am preparing IDT for Group 2 of CWA.I am following Bangar.

There are so many rules in IDT that I find it difficult to remember even one rule. I am planning to give it in Dec. By Oct end or nov end I will be able to complete only one reading of IDT, that too if I read only IDT daily and extensively. I am working full time also.

Can anyone please suggest what can be the best way of preparing 3 subjects OMIS,IDT and CMA for CWA Inter.

Regards,

Prachi
