Ca and cs

If anyone here doing or have done ca and cs both, please reply:-

1. if someone is doing articleship of ca (Ipcc passed) and cleared cs executive.  is the same training countable for both the courses?

Yes , I am doing CA final and passed cs executive both. The training is not countable for both. Articleship is different so is ... cs training.

2. Does the duration of 15 month training reduced in any condition if he join traing before or after cs professional.

not sure but 3 months training got exempt if you have done Job for a year.

3. Can he get exemption from cs training? if yes then how?

question not applicable .....

In cs, we can start training after final (professional). Why can't we do so in CA  too?

 because after CA we become perfect na ... our articleship give us the experience of what we read in theory ..... 

waise too much complicated question ....I won't mind if you ask this q from ICAI
It would be better to having option of doing articleship after clearing ca final or half articleship before final and half after ca final.
