The DMV has the book to read for the test. Each section has 'sample test questions.' Spoiler alert, those questions are all on the test. I read the sample test questions and if I could not answer, read the pages that answered the question. Took me 15ish minutes to read the book and I took the test right after.
If you would like, send me a PM with your email address. When I was doing my production week, the supe that rode along emailed me the pretrip speech that he has to perform as part of being a feeder supe. I do not have a FT feeder gig, I cover vacations in an outstate building, so I work feeders when the chance comes up. I read through the pretrip dealio the weekend before a job starts and I feel way more confident going to work that week.
