I have joined SubodhShah's class at Pune for DT for CA Final Nov 2010 attempt presuming that the coaching would be as good as he imparted for PCC, which incidently I cleared in first attempt securing 58% in DT. But to my dismay I have found that the coaching for final is below par with lot many holidays and no practicals. Anyone can suggest which will be the best book for self study for DT?
