Basically, there is no restriction regarding the number of attempts in Integrated Professional Competence Examination. Candidates may write the exam as many time as required to qualify both groups.
Now, as far as the validity of registration is concerned, each registration is valid for four year. If a candidates fails to qualify the examination in four year period of the registration, he/she will have to re-validate the registration by paying a minimal amount of fee which is Rs.400.
Since you have registered for the course in the year 2010, you may write the examination till 2014 and after that, you will have to re-validate your registration only if you have not qualified both the groups of Integrated Professional Competence Examination.
