So... When they leave the simulation, will they have any effects on the body from the fight? Or because it's a simulation is it just a memory. Also, when your eliminated, do you automatically wake up in the class or when the whole simulation is finished?

It's just a simulation, so the only lasting effect will be the memory of the simulation. Once you're eliminated, you have a sort of out-of-body experience. You can see what's happening around you, but can't influence it in any way.
