I have been training on SkyTest and I have been getting about 95% every time on Dynamic Radar Test, but on Radar Control Test I have been getting only about 75% - 80% Should I be concerned or is it normal because it's just harder ? (it does seem harder but not that much, and also sometimes i get weird notifications on RTC like collisions of flights that are not on the map etc. so maybe it's just buggy a little ?)

I am having my FEAST II Test in a week, I practice on SkyTest and my question is what scores should I be getting to be sure I pass, because on the graph with my scores it shows that I am well above the "average", but im not sure if those average scores are any relevant.
