Eric is very passionate about math and has a lot experience teaching math.
Andrew is one of a kind. Very good at explaining and trying to find a way for you to understand any concept. He is also very funny and can relate the material for you to understand and maybe think about a real life example. He is also good at finding what exactly your struggle maybe, either mathematically or just misinterpreting the question. I would suggest working with Andrew if you want to receive in "A" in your desired course.
Kemaray does an excellent job with my daughter. He is very patient and helps to reinforce the topics she covers in school. I highly recommend him.
