The PPL Confuser gets pretty close to the real questions.
If you work through that enough times to consistently get 90%, you will have an easy time of the real exams.
And remember you only have to
pass - you don't have to get 100%
90% of the PPL theory is irrelevant anyway. What matters is your attitude as a pilot, and how much personal interest you invest in flying to pick up the really useful information.
