From High School to University Math. Also any Math tests - GRE, GMAT. My name is João and I have a Masters Degree in Pure Mathematics at the ETH Zurich. I was a phD student at the University of Oregon for 1 year, I taught Calculus and Statistics there, but for personal reasons I had to move back to Portugal. My passion is learning and teaching mathematics. I've been tutoring math for 2 years now. I will help you think about the concepts properly and gain the right mathematical intuition to solve the exercises.
