Dear Mkshah,
Thanks for the reply , so the answers are :
1) Submission of DELF(B2) results would be calculated on post 6 Dec,2011 criteria for myself.
2) Being a retrospective decision , the scores for Delf exams would be analysed at interview stage for scores submitted before 6 Dec , 2011.
even you being applicant before 5th dec, 2011,this new criteria will not be applicable for your DELF B2 result too.
Your application will be treated according to all criterias applicable at the time of your application. It will not be effected with any changes thereafter, unless it is specifically notified officially by Your BIQ / MICC.
This new criteria will be applicable to all new applications submitted post 5th dec 2011.
I hope I have clear ur concerns now, buddy.
Thanks
Varun
