Questions are moderate and one can pass easily , its all about your approach towards the exam. Many students find CPT questions tough but when they pass CPT and qualify into PCC then they think CPT was really easy , only little effort was required. Same way when they study for PCC he/she thinks its damn tough but once they clear the exam and qualify into final then they think PCC/IPCC was just a simple exam and people panic unnecessarily. So its about your preparation for the exams...if you prepare well , questions are always easy.
However there are some mistakes due to which student fails in PCC/IPCC .
like writing slow in the exam .. most of the time they cant even finish the questions and eventually they could only attempt around 75-80 marks questions. This is because lack of practice and improper time management. hence i would say practice problem sums at your home as if your in exam hall , be quick and try to complete a sum within 15-20 minutes.
