Hello Guys. I am Usman from Lahore and i am 18 years old and now i am a student of 1st year of BS in Computer Science. I appreciate the passion and determination of the guys whom want to join Pakistan Armed Forces. But there is one problem that selection in Armed forces is very very tough and only best of the best are selected by ISSB specially for GDP in PAF. No one knows the selection criteria of ISSB. Actually i applied in 121 GDP Course because i had a great passion to join PAF as GDP. After clearing my initial IQ , writen and medical test i appeared before ISSB in june 2005. There were 35 more candidates with me whom came for the same job at ISSB from different cities. 1st day was psycologist day in which psycologist checked the candidates in writen tests whom had to be performed in very very short time. Second day was GTO’s day in which he checked the abilities of candidates by physical acitivities and third day was also GTO’s day. At fourth day only 3 of candidates were called for re-interview and after that they sent us back to homes. After 4 days i got the letter with my original documents that " I am not recommended by the Board". After some days i also got to know that no one from my batch was selected for GDP including re-interviewers. So result is front of you now. In PAF the candidates selected for GDP were mostly from PAF College sargodha and PAF college lower topa murree. In a year two batches are inducted in GDP Courses at PAF Academy Risalpur. One is inducted in may and second is inducted in october. And in a single batch of 45 cadets 30 of them are from PAF College Sargodha or Lower topa and rest of 15 are civilians .And at least 20 to 30000 candidates applied in a GDP Course from all over pakistan and only 15 are selected. So now u will get to know that how tough the selection is. If u applied in a GDP Course u are selected by ISSB luckily then u are 50% selected. Because GDP medical stardards are very very tough and then u have to clear a Flying Aptitude test. So in my oppinion now if u r not from mentioned PAF Colleges then it is 5% chance that u will be selected for GDP. Eye sight must be 6 by 6. (5.9) will also be rejected. I had just passed my 1st year examinations when i applied. Physics is mandatory in FSc for GDP and only FSc pre-engg , pre-medical and ICS with physics can apply. This is the common and general information about GDP selection in PAF. For further information plz contact on my above mentioned email [email=“[email protected]”][email protected].
