Hi Abhi,
I am glad that u have shared your problem with us. It realy takes courage to share self weakness with others...
I truly appreciate Aamir perspective and i will suggest you not to quit at this point of time. Don't think that u failed in last few attempts.. FAILURE DOESN'T MEANS END, IT ACTUALLY SAYS THAT THERE IS STILL SOME AREA FOR IMPROVEMENT, WHICH U HAVE TO FIND AND WORK ON IT TO OVERCOME FROM.
Try at your best atleast once more not just to pass pe2 but to prove yourself...
Luck also plays important role in one's life. It could be that your luck is not stricking in CA. If you realy want to quit CA you should quit but atleast try once to proveyourself.
One more advise - You can go for CWA or CS where your ca studies will help u a lot. These two professional courses also have great scope today.
Thanks
