I hope this isn't true. First of all this is just a.. beginning test, before the real training has started so in my opinion it's not realistic to expect the maximum. Besides I think in some cases conflicts just can NOT be prevented. E.g. one of my aircraft was surrounded by 4 other aircraft, flying at flight level 100 (2 airplanes), 200 and 300.. So even by changing the level I couldn't escape the conflict....
It didn't seem soooo hard, however I can't say I'm totally satisfied...
