eco

If you will read the contents of module than it is more than enough.

All the best...........

Txtbook is enough but u must take updated notes on ECO, in delhi you can get the latest data from Mr. pankaj gupta, @ sanjeev varshney classes, becouse questions are based on latest and updated data

i reside in mumbai. i wanted a textbk as there are very few mcqs in module to solve.
