better to give 2nd group first???

I dont hav much tym to study both the groups as i am not well prepared..

I am giving both the groups of ipcc may 2011 xams.But to the contrary of popular approach, I am thinking of preparing 2nd group well as it wud give me ample time to prepare well for 1st group in my 2nd attempt..

moreover i can even utilise d tym wich i wudnt get if i wud clear 1st group as i wud den be doing articleship...

wud dis make any diff in d duration of course?? willl i lose six months bcoz of dis as i have to undergo 3yrs articlesship after i clear my first group???

please reply as soon as possible.....

thnx in advance... :-)
