Exam time

if u start now u can easily clear grp 2

make sure u study the entire syllabus 

I suggest you start preparing ISCA and Costing right now because, their syllabus hardly changes. Also, simultaneously prepare basics of DT like Asst Procedure, Heads of Income, Wealth Tax. Rest wait for updated edition applicable for may 13. Even for IDT, prepare basics of Excise and customs. Else wait for updated edition. Doing this, u'll surely clear grp 2 in may 13 with flying colors... all d best.
