When To Seek A Tutor:

When you need to learn time management and study skills at the beginning of the term.
When you need help understanding the homework.
When the instructor's office hours are booked.
When you need help understanding concepts and ideas.
When you need help to prepare for a test.
When you are falling behind.

What To Bring To A Tutoring Session:

The textbook.
Notes, syllabus, past tests and quizzes.
Homework or troubled problems.

What Not To Ask A Tutor:

Don't ask a tutor to do the work for you. Learning is a process and working is an integral part of it. If you don't work you won't learn.
Don't procrastinate. A tutor will not cram with you. A tutor's help isn't enough to learn in one evening what should have taken a month of methodic work. Tutors will complement your work, provide you hints, suggestions, etc. but will not replace good, honest, hard work.

Good Attitudes Towards Tutoring:

Try your best to understand the material before coming to tutoring.
Be an active student in class. Ask questions, participate in class, etc. Many questions can be asked right there and then to the instructor.
Read your syllabus. Understand what's expected of you in each class, and make sure you find and remember deadlines and other special dates. Get your tutor ahead of time.
Your instructor is almost always your best resource. Try asking your instructor first, as soon as a question occurs to you. Bring those responses to the tutor in case you didn't quite understand.
Form and maintain a study group.
