I recommend spending developmental time making plant rounds with Operators. Learn that Outside The Control Room stuff, your License Class will cover the Control Room choreography in excruciating detail. See how the components operate in the plant, equipment locations, local panel locations, bus arrangement, etc.
I'd like for you to hand crank a 345kv switchyard disconnect and see your shadow in the gravel from the arc. There are numerous "calls" made from the Control Room that require substantial safety awareness and pose considerable risk.
This is very important and will NEVER be seen on an NRC examination.
To learn from operators, I advise you to respect and acknowledge their experience based knowledge. Most of the better operators have an ego, and they like showing off their detailed knowledge to an appreciative audience. Most Control Rooms ALLOW conversation related to plant operation at the panels. Use this and visit the crew to learn something new. Many things are TRIBAL knowledge, and this is the ceremonial grounds appropriate for transfer of enlightenment.
You won't get it in a classroom.
