Student reviews

Wolfgang Hamadeus Mozart
Very good teacher, not just a knowledgeable person. Always on point and has a lot of patience. Even dummies like myself can't miss thanks to her approach.
Laurent Boquet
Mayra teaches my 15-year-old daughter. She is an excellent pedagogue and takes her mission of teaching chemistry to my daughter seriously. She is also very friendly, and my daughter feels like she's studying with a friend. The lessons are prepared in advance, and exercises written very neatly are sent after each lesson. The lessons are given in French, which is not a problem at all for Mayra. It is clear that this teacher has a passion for chemistry and a desire to share her knowledge. The quality of her work does not diminish even after several lessons. Respect for her involvement, professionalism, and kindness on top of that!

Estoy muy contenta con las clases que he tomado con Mayra. Prepara muy bien las clases con antelación y orden, explica con detalle, toma interés por tu necesidad concreta. Muy formal con las horas. Muy buena profesora. Me ha ayudado muchísimo. Fue un acierto total dar estas clases de Química con ella.

Hola mi nombre es Jose Angel, he sido profesor en la Universidad mas grande de Venezuela por casi 40 años. He pasado a retiro y me he residenciado en España, por lo que quiero transmitir mi experiencia mediante clases particulares, basadas sea en comprensión teórica o resolución de problemas, con seguimiento personalizado. Las clases se dictan en la plataforma Classgap, utilizan interacción constante con los participantes, mediante preguntas, presentación de la resolución del participante para identificar y corregir errores o sitios donde el problema no se esta analizando correctamente y por que. Solo algunas materias: Introducción a la IQ, Mecánica de Fluidos, Transferencia de Calor, Transferencia de Masa, Operaciones de Separación, Tecnología de Partículas. Especializado en Uso de Excel para resolución de problemas.
