Assessment Year 2015-16 will be applicable for both June and Dec 2015 term.
There is a simple logic. Assessment Year in which exam is held that same assessment year will be applicable. In the given case June 2015 and Dec 2015 exams are held in FY 2015-16 and therefore Assessment Year 2015-16 will be applicable. Hope your doubt is cleared for once and for all.
