Mathematics 1st and 2nd grade secondary education. Since I was 18 I have been tutoring math and science. Fifteen years, that is going fast. First as a student job and then as a side job. I traveled halfway around the world and now I am staying in South America for a while, from WiFi connection to WiFi connection to give tutoring math, physics and chemistry. I have supervised students from ASO, TSO and KSO. I also successfully helped gifted and children with autism. See you soon!
