Is bangar compiler sufficient for ca final idt ?

I have studied it and its very helpful but require a huge amount of time. illustrations are good to understand concept. overall i find it very helpful. you can go for it.

Thanks, but I wanted to know if the compiler alone is sufficient for preparation. The main book is huge.

Compiler is good too. if you have knowledge of the concepts then there will be no issues plus always read the study and practice manuals.
