Okay, as a tutor, i always tell my tutees (is that even a word? haha) to do the homework, go through the lecture notes, do the study guide, etc. on their own first and then come to me with and questions they might have. I also email the professors of the class(es) I'm tutoring to let them know that I'm tutoring and ask for a syllabus. It's worked out well; currently I'm tutoring genbio students and, as an example, one is having problems understanding meiosis, so I'm going to give her an old copy of a meiosis worksheet we got in genetics that i think does a better job explaining things than her notes/textbook.
You might want to contact your tutor before the actual time you meet and give them a sort of head's up on exactly what you're struggling with, so that s/he can prepare information and the tutoring session will be more productive. Even when someone has taken a class (i know in our school student tutors must have taken the class and gotten a B or better before they can tutor/ta/be a study group leader), when they're put on the spot with a vague or weird question they might not be able to help you as well as they could if they had a chance to do a quick review themselves beforehand. Same goes with professors; you might want to email them saying "I'm having problems understanding concepts X, Y, and Z, so I would like to arrange a mutually convenient time where we can go over these concepts." I don't know how that works in bigger schools, but I go to a small libarts school and the professors are generally very accessible and are happy to help students that ask.
That's really weird that your school sent you to a tutor that never even took the course though. I would definitely try looking elsewhere for a tutor, or try to contact your professor.
