what is this?

A rehearsal in which the actors deliver their lines and perform the action at a much higher rate of speed, usually trying to run the rehearsal at "double time". Used to help with the common problem of slow or dragging pacing. Once the actors have performed at the much faster pace, they often will not return to the problem pace of earlier rehearsals because the pacing will be slower only in relation to the faster pace of the Italian Run-Through. Also referred to as a "Russian Run-Through".

I hope that helped. I usually hear it called a "speed through"

Have fun at rehearsal! :)

The answer above is exactly correct.
The only comment I would make is if you have questions about the rehearsal schedule or, more importantly, the play itself or your character, ask the director. He is there to help you in any way he can.
