As per new announcement about CA Examinations on ICAI website it is ordinarily declared in second fortnight of January following the month of November in which the Examination was held. That is the only official hint by The ICAI so far.
Council meeting is on 17&18 Jan 2016 and hence result will be announced between 19 -21 January 2016
