Earlier it used to be ,33, I guess.In the past for many years they did not conduct PMS yearly.Hence,deserving candidates could not sit in exams as they were over-age by the time when ultimately exams were conducted.Last year too only 4500 some students applied for PMS,so therefore if PPSC relaxes age further by 5 years then they will get more able candidates.When for every other grade-17 post there is relaxation of 5 yrs , then why it is not applied to PMS exams ?
