it is not an exam
I assume you are already in the system, and your employer will have under the counter all the questions, and all the answers.
All the airlines have published crib cards, with all the answers.
Most corporate operations have these also.
There is no need to fear the "exam", my only advice is to have a good shower before, and if offered accept the early sitting, as all the good questions will have been taken from the buffet.
have fun.
