Help on Ability/Aptitude Testing

Alright guys, few months ago I applied for a Apprenticeship at a well respected British company.

Out of around 500 I've been invited for a ability testing. I'm willing to quit Wellbeck Defence college for this opportunity and I need your help.

This being my first time applying to this sort of thing. I'm not sure how about a Ability test goes down, I'm pretty certain its a aptitude test. But I need pointers from people who have maybe faced one these tests...

 

I think i took this test for the United States Navy Nuke Program. I studied a Nuke Test Guide beforehand and I made a decent score. Im sure you can find one online with a little bit of googling. It was over a year ago so I cant really remember. Good luck!
