Hope i'm not teaching to suck eggs, - anyway you can buy all the questions /answers in three telephone directory sized books also oral & practical guides as well.
The 'school' i did my A&P cert at, simply sat you in room with the books .We highlighted the correct answers only ,then simply read the questions/correct answers repeatedly, did lots of exam papers & when we hit 90% + (in all three papers) we did the exam & passed easily.
The oral followed the format set out in the oral & practical guide. The practical varies from examiner to examiner. With the bigger schools they will use the same 'pet' guy for oral/practical so the format should be well known.
If memory serves there is guidance as to the types of practical tasks that should be undertaken in the oral/practical guide.
