Successful tutors DO NOT:

• Teach magic tricks.
• Expect the student to hear and remember everything they've said.
• Say, "This is easy" or use any other phrase that might imply the student is not smart.
• Put down or criticize the student or their abilities.
• Solve the problem or give the answer. The student should be holding the pencil.
• Criticize a teacher or the assignment.
• Go too fast.
• Make off-color jokes or suggestive comments to students.
• Use profanity.
• Waste the student's time talking about themselves.
• Over socialize with other tutors when not tutoring. When students think you're busy talking they'll be discouraged from asking questions because they don't want to interrupt you.
