I did the test 2 years ago so I don't know if it's changed much...but yeah it's not that hard - its essentially a combination of the L's test (knowledge test) and the P2 test (hazard perception). The only difference is the knowledge bit has more statistics and stuff that you need to look at the handbook for, and the hazard test is essentially the same, except in one sequence, there may be multiple hazards, so you have to touch the screen several times (ie, might see a cyclist, then a truck, then a parked car etc).
