I went to a recruiting presentation to my Uni. The HR talked for about 45 minutes about the work they did at the company and about the lifestyle of the workers. During this presentation he also explained the FET program in detail making sure that we knew it was no usual job. After the presentation we did a test on math and physics (basic stuff) and he mentioned they only took the best 20% of the bunch. This test was without calculator and covered things from basic physics to pulleys to mechanisms; again, in a really basic way. My advice for this is to round up numbers and really work your math.
