Decide ahead of time what your goal for the tutoring session will be and tell your tutor exactly what you hope to accomplish within the session.
Do you simply want to do your homework with the tutor watching so that they can catch any mistakes? Do you need to have earlier math homework explained to you? Do you want a comprehensive review of the whole chapter right before the math test? When you know exactly what you want, the tutor can customize the session just for you.
Your math tutor should be able to judge how much can reasonably be covered within the tutoring session. Don't be disappointed if your tutor says that you can't finish everything -- work with your tutor at the beginning of the session to decide what is the highest priority, and what can be left, if necessary, until next time.
Do not spring a whole new set of problems on your tutor five minutes before the end of your tutoring session! ("By the way, this was tonight's homework . . . ").
The beginning of every tutoring session should be a quick (less than a minute) discussion of what is to be covered in the lesson.
