I got registered in cwa inter on 30th may 2011. I completed group 1 of inter in dec 2011. I appeared for group 2 in dec 2012 but failed. Now I want to appear in June 2015 exam. My queries are:

1} For how many years registration is valid for cwa inter?

2} I havenot appeared in any exam conducted by ICWAI in last 3 attempts. Will it affect my registration in CWA?

Reply ASAP.

Thanks
