My name is Pablo Rivera. I studied Mathematics and Physics in Universidad Complutense de Madrid and now im living in Mombasa, Kenya. Since 2015 I have been working as a extracurricular teacher of Maths and Physics for any kind of level, secondary, high school, university... I worked with very different students with a big variety of necesities and objectives. Due to that my classes are personalized, adapting them together with the student to his/her requirements. Sorry the presentation video is in Spanish :)

Espectacular profesor. Se nota que le gusta enseñar, por lo que al final te termina gustando a ti también y le pones las mismas ganas que él. Lo recomiendo encarecidamente, ¡no os arrepentiréis!
