Enjoy your training for your PMEL usmc-sgt. My multiengine training was some of the best flying I've done so far, especially when you start training on how to deal with single engine emergencies; engine failure below Vr, above Vr, when to abort or continue the takeoff.
My instructor has told me plenty of stories of students that are afraid to maneuver the aircraft while practicing single engine operations. For example, 30 degree bank turns or even steep turns because they are not used to flying an aircraft in that type of situation. As you continue your training just remember the two most important items when flying single engine: AIRSPEED & DIRECTIONAL CONTROL. If you have those 2 items under control you can literally do whatever you want to the aircraft. Heck, you will even be able to do a 50 degree steep turn…....but might not be able to hold altitude
Enjoy!
