I have gone through this thread and I have also done some research. Here are some sites that offer something similar to what we shall be tested on. Unfortunately they are charging a fee and you also need a joystick.
AAT | AirlineAptitudeTests.com - Pilot Assessment Software
PAT | PilotAptitudeTest.com - Practise for COMPASS Tests and PILAPT Tests
Another thing, FEAR should not be an option if you want to ace this test. I have discovered its what kills many people in this stage, therefore, even if you've never seen a joystick, please stay calm and try to give it your best shot.
All the best guys.
