Exemption

you hadnt prepared yet and now u r planning for exemption.. amazing and strange... 

i wil say for this attempt just forget.. and prepare for the next attempt.. a true advise wil b this

cant say that go ahead work hard and all.. because nothing wil gonna work in two to three days dear....if u hadnt studied earlier...

u hadnt write that before ..

so just stays confident, and try to quote sections case laws in exam .... all the best

achha.. May b u know far better... so dont want to comment or make it an argument.. sorry for my advice... Good luck..

Stil wil say write the reference of case laws....

Ruchi ma'am if writing the case law doesnt help in getting marks than you may write CIRCULAR Numbers and Notification numbers....
Quote section with sub section clause and sub clause
also relate your answers with other subjects also.... I think u must have prepared well for IDT
and if you have prepared just for IDT than u must write the circular number...

Best of luck
