@ momo

rules of khyber pakhtunkhwa PSC for PMS are as under

No candidate shall be summoned for Viva voce test unless he has
obtained at least 33 percent marks in each optional subject, 40% in the each
compulsory subject and 50% marks in the aggregate of the written portion of the Examination.

so, you got about 651 marks. yor are nor failed in compulsory, nor optional nor failed in aggregate. whats the logic behind your problem?
