I was doing some practice ones the other day. Seemed fairly straight forward if you have a bit of driving knowledge. Be sure to read up on road signs, different types of crossing, stopping distances for certain speeds (30, 40, 50, 60, 70) in dry, wet and ice/snowy conditions. Im not sure if its just me but in 17 years of driving i seem to have picked up most aspects of the theory test from just being in the car with parents, friends etc.
On my first attempt i got 42 of 50 and then got 49 of 50 so i was happy with that
Good luck anyway, hope you pass
