I also used Latest Pilot Jobs! was a good resource for the ADAPT Test. It wasnt as bad as I thought if im honest, the physics and maths part, you could brush up a little, just learn the basic GCSE stuff like basic circuits, just give it a read over. Have a look at a ADAPT test being done, on youtube btw, itll give you an idea of what part of the multi tasking ADAPT test is like as its the same software
I didn't actually pass the first time, I failed in March due to the Fixed wing which is sort of like a flight simulator, where you have to maintain an altitude and fly to certain points. The explanation of this is clear enough when doing it, I just reckon I lost concentration at this part. Even though i failed this, CAE gave me the option to move onto part 3 and retake the Fixed Wing part at the same time after 3 months.
Overall, check Latest Pilot Jobs and dont be too nervous. I definitely over thought it but I passed and I start at Oxford January 2nd!
Good luck!
