jr selection exam

so I applied for a job as a station attendant with jr west on a lark, not at all expecting to get anywhere. now I'm going to be taking a selection exam but I have no idea what kind of questions will be on the exam... just wondering if anyone here might have some ideas?

Have you asked the people in change of the exam? Or doesn't it say on the notice they sent you? Employers often give out information such as "There will be paper exams of ippan-joushiki and English, as well as a face-to-face interview." or something like that. Then you will know which text books to refer to at your local book store. Feel free to post here again with more specific questions.
