I've been a Math Tutor for the last 10 years and 6 of them is done via Skype. My specialty is High School Math and SAT in particular. I've scored 800 (out of 800) on SAT Mathematics level 2 this November 2019. There are more than 99 A+ reviews on another platform. I took the following tests: TOEIC (2018), TEFL (2018), and TOEFL (2015). All my students have gotten desired grades on their exams and improved their scores on tests. So if you want guaranteed result - welcome aboard!
