I had send a query to CNO and this is the reply I got....
MELAB will not be accepted for registration as a nurse if you are registering after January 1st, 2013 even if you passed the MELAB test in 2012.
Only academic version of the IELTS and CELBAN will be accepted for evidence of language proficiency in English.
I doubt whether I will make it............................... :'( :'(
