The nicest man I have had as a tutor yet. Took plenty of time to go over each question I had thouroughly, and made sure I understood before moving on. Very personable and made light hearted jokes to make me feel better. I feel a lot more prepared for my exam than I did before this session. This guy deserves the world.
