Discontinue of Articleship

hi dears,

I am a PCC student who has completed 2 yrs of articleship(including the max eligible leave). I am not being able to clear the exams since past 2 attempts. Now, i am of the opinion that i need to clear the exam first, as continuing the articleship period is futile, if i dont clear PCC. I want to take a kind of break from articleship till i clear my PCC exams and continue after clearing the exams. I want to know the options available to me, in case my principal does not agree to mutually give me the break from articleship. Can i discontinue/transfer/go on secondment? Please help.
