Yes, there was no clarity in it. But what i know is for claiming training exemption, one should fill Form T-3. And Form T-3 is to be filled by such students who are already in employment at the time of registration. After completing the CWA Final exams, you can use Grad. CWA status after your name. Only after completing practical training requirement, you can be eligible to apply for Associate Membership. One of the requirement for getting exemption is one should work in an organization having turnover of Rs.5 crore in the previous year.
But I was wondered, it seems you are already in CA IPCC and CS courses. Once you start articleship in CA, you are not allowed to take up more than one additional course at a time. Which means, you cannot pursue CWA after you joining CA Articles. Because by that time you already having CS course. For this one course also, you need to apply to CA Institute in Form 112 and should take permission.
