Hi all, I'm Rahul and i cleared my CPT with a score of 140 in June 2012. I've started going for coaching classes for Group 1 subjects and now im thinking whether to write II Group also in May 2013. I've not joined regular college for B.Com too. But im doubting my abilities for clearing both groups as i have not spent much time with the books during school days although i got 90% in boards. So please advise me on whether to write both groups or not and also some tips on how to approach the exams.
