plz do clear my doubts

first of all congrats on clearing ur first group.

an article trainee who is in his/her articleship training in the last 6 months can give their final exams . i.e 2 and half years limit for writing ur final exam 

leave is included in ur training period

As per latest notifications an article trainee can get transfer only in his/her first year of articleship and the limit is n number of times (only in first year ) then the remaining period u cant change ur auditor and u have complete ur training under only one auditor.
