Rajesh tayal idt ca final good?

If we talk about the IDT Book:

Bangar is the best for IDT.

Then, comes Vineet Sodhani.

And then, Rajesh Tayal and others.

Now, if you take coaching from any good tutor, his notes will work fine. Thus, Rajesh Sir's book will be more effective if you also take coaching from him.

Rajesh Thayal is good choice

tayal's book is very good

tayal's book is not good for concept clarity and basically self-study. there is no use of his book if you haven't taken his coaching
