AOA..!!

Dear seniors I've masters in English and I've been taking exams of PCs since 3 years and so for I've not qualified unfortunately even a single one. First i thought that perhaps i am not serious in preparation and that's why i stood UN qualified.

But recently i prepared for the post of Dep Dist Acount officer, dputy accountant and for Tehsildar well from GK books by Advance and Carvan Publishers much. As well as i prepared the most recent events from ajmal forum nd many other resources. But once again i stood fail and thrown aside.Why always i couldn't get pass???

Seniors please guide me how should i prepare for PCs 100 marks paper as now it seems to me much more difficult to pass and it would not be out of place to say that i am disheart.

I always prepare for Carvan and Advance puclishers but couldn't ever pass any PCS test.Please tell me books which will help me to pass my test and other resources like notes or any link on internet..

Seniors please do reply and guide me how should i prepare for PCS.
