Dear student,

If you want to give yourself one more chance then go for it. Give your best this time and do whatever it takes to crack the examination. But if you think that it is impossible for you to crack the examination and it will be an impractical decision to put pne more year for the examination then find some other options for yourself. Many students put many years to become a CA. But many crack it in two to three years on an average. If you feel you are not fit for it then don't waste one more year on it and invest it somewhere else.
