I failed twice in CA CPT. The first time in december the qn paper was very tough. I got 80. But this june, the qn paper was comparitively easier and i wrote it well and was expecting to clear the exam. But to my horror, i didnt clear it and got 79 marks lower than the previous exam. But i wrote the exam really well. i dunno what happened. What shall i do? please advice.
