can a person give CWA both groups together????

Yea Sure

you can Give Both Groups together provided that you have cleared your  CC papers, GD and ITT Programme before appearong for the  exam.

to know Basic Difference between CA CS CWA Visit the following link:

 CA vs CS vs CWA

THERE IS NO MUCH DIFFERENCE, BY DOING ICWA U CAN HAVE BETTER OPPURTUNITIES COMPARED TO ONLY CA STUDENTS

you can Give Both Groups together...

An employer would certainly prefer a CA+CWA over CA...that is the only difference...and reason is very simple.

All the Best
