Isca coaching?? or self study??

Coaching will help u buddy. If u can do it, den u must do it. Dinesh Madan is the best book for IsCA. Just support it wid Practice manual.

i will suggest self study. and of course dinesh madan book is best for isca.

Yes, self study in ISCA should be okay, because you will be attending other subject classes. Institute study material is advisable, so that it can fetch you good marks, because this one subject is pure theory and hardly any application of mind, but you are required to present the paper in the language of institutes material.

Thanks frnds... will buy dinesh madan material.. And it is difficult for me to read institute material.. such a bulk quantity na.. For IDT best coaching in Hyderabad..??

No idea ! I m from Pune.

I would also suggest you to take a look at Manish Valeccha ISCA books. I read Module once and then read whole subject from it few times. It is neatly presented.
