The goal of any tutoring experience is to improve the knowledge or skills of the student, and the relationship between the student and the tutor is paramount to that success. Not unlike teachers, tutors are held to high standards both ethically and professionally.
Most tutors will work dilligently to help each student succeed, but do not expect your tutor to do any work for you or help you to answer questions on a test that is yet to be graded.
In addition, do not expect your tutor to know everything, just like classroom teachers, tutors may need time to prepare for a session. This does not mean they are not capable of teaching the material, only that they need extra time to insure that the method of instruction used is best suited to the student's individual learning style.
