Their website has a practice test, and for the most part everything on the test is on their practice tests. Its just a lot longer and they dont give you a lot of time for each section. Study algebra a lot! Everything else is easy. The interview is with a bunch of Union members on the board. They mosty ask you about your experience, what you think linework entails and why you would be a good fit for the job. Think of a bunch of questions to ask them, they like that. Like, how the boot camp works how the schooling is and steps of pay etc. The written test gets you an interview, the interview and expericence is scored and thats where you go on the list for 2 years. Ive been on for just over a year. Goodluck and where are you planning on applying?
