I have failed in my PE 2 exams. I have given the first group this time and had decided to give the second group in Nov. I got above 50 in audit and law and got just 28 marks in accounts but thats not good enough for an exemption.
Should I re-appear for PE 2 or leave CA completely.
I am in the final yr of my B.com and was thinking of doing MBA. So should I quit Ca and prepare for entrance test of MBA.
Please tell me whether CA is meant for me. I got 65 pc in PE 1 in the first attempt and I am an average student in my regular studies.
