Pass the examiner $50
The test is easy IF you know the material...
As others have mentioned, study, study some more, and when you think you know it all, read the material over again.
Study. Read the manual cover to cover several times.
Read the Highway Code a couple of times before. And when you are sat at the computer, just click the mouse once when you see each hazard - multiple clicks confuses the memory and you will fail.
Learn the book, like everybody else who passes.
Studying always helped me pass tests.
Study, study study.
