In your booking confirmation email you will see address links to NATS ATC motivation pages. In these pages there is information regarding ATC and what you will be quized on during your test. If you read and learn all the information supplied in this leaflet you will have no problem with the test, inclusive of all the aircraft listed at the end.
If you have any problems accessing these pages let me know and i will find the link for you and send it to you.
Good luck
