Online Electronic Engineering Quiz

Engineers are the back bone of Pak Army because in any war situation, Engineers help Pak Army to keep on advancing to the difficult areas. In Engineering branch, soldiers are also given training regarding electronics equipment for maintainance and smooth functioning of the defence.

If you are interested to join Pak Army as Engineer in Engineering branch then you are at the rigt place for preparation of all intelligence and academic tests. Here, all types of tests pattern and procedure for online applying is given. 

Past papers of Electronic Engineers are given here to pass the initial tests of pak Army commissioned branches Tests. Learn here about Intelligence Tests, Academic Tests & Interview questions with the whole procedure here at this page below.

For the preparation of all tests, Click Here and for notes Click Here. Further detail may be taken at any time. Contact us for more detail.
