For anyone reading this, I've known this guy for ages, he is most friendly and dedicated guy I know. Last year I asked him to tutor my sister for chemistry and biology in 2009. She went from a 74 and 79 in Chem and Bio in year 11, to 96 in both subjects in year 12. I was told that he is extremely friendly and dedicated towards teaching. If you are to choose private tutoring over any tutoring college, then Samuel will be your reason. If you are a year 11 or 12, then quickly find this guy because you wont regret it.
