The percenatges have gone up in the recent few years...the trends are improving..its not a tough thing now for any average and hardworking student..and more than pass percentages what students should look for is the oppertunities and venues available to them after becoming CA...which have increased like never before... In my opinion they are in plenty now.The demand for CA is on rise be it in jobs or practice...and the earnings have become handsome too. So anyone need worry about pass percentages only since those who are talented are definetly going to clear it.
