I feel much better about myself now, I got a 98. really.
There are a few questions that are technically incorrect, but in all the questions the right answer is clear enough, except for one (I am certain it's the one I got wrong): In a naturally aspirated engine, why does the air enter the cylinder?

Spoiler for choices:

B: From the suction from the piston moving down, or C: From atmospheric pressure pushing it in. I chose B, because if the piston wasn't moving no air would move, but I bet they wanted to hear C

Don't peek at the spoiler until after you've taken the test.!
