flying lesson - crosswind takeoff, emergency procedures, ground ref maneuvers

Flew today, did some ground ref maneuvers and then we did a little emergency procedure practice when my instructor pulled the throttle to idle and I had to do an in-flight engine out thing. I need to take the FAA written exam this weekend but work stress (which is happening now) can really impact my performance on that so I'm not sure what I'm going to do yet.
