@Budding,
At FTE there are four different written tests. Numeracy, which requires algebra, trigonometry, fractions, percentages and geometry. There is also numerical reasoning, verbal reasoning and maths and physics. The maths and physics contains lots of speed, time and distance calculations along with other mechanics. FTE send out a preparation pack before hand which pretty much covers 60% of what is in the tests. However, even if they didn't provide candidates with a prep pack, if you dig around hard enough then you can usually find some information online as to what to expect at the FTO's.
