congratz on passing stage 1! I believe that OAA uses the compass/ADAPT testing for stage 2. I did a compass test earlier this year. About 50% will pass the compass test, at least where I did it.
You'll probably pass it if you go in well prepared
You could try this test which is pretty much identical to the real compass test:

I passed the test with 39/42. 24 was the minimum score for a pass. Just relax and concentrate well. Practice your math and physics well. If you have a joystick you can try a few online games to improve your hand eye coordination
