Nick,
The exam content is covered in class. Take good notes. Don't worry if you don't understand everything because when you go out in the field training, you will see the practical application of them. This will set you up good to pass. Just remember, it's not the rules you get right that will get you in trouble, it's the ones you get wrong.
Don't get mixed up with some drunk, who ends up fired, or gets fired for not passing the exam.
In training, your schedule will depend on what job you are training on. After you finish, everything depends on what job you can hold. It might be a switch engine, nights, with Tues. and Wed. off. You might also be on the spare board. If that is so, you will have no schedule.
