Online Math Tutor with over 6 years of teaching, currently becoming a medical doctor!

Hello! My name is Sydney Topfer. I have a degree in Psychology from Tulane University. I am currently in my 4th year at medical school and applying to pediatric residency. Before medical school, I was a 6th grade math teacher. I love learning about students strengths and how best to serve each learner. I know every student has the ability to succeed and I look forward to watching them achieve their goals. I am a very organized person and will structure my classroom based on how each individual student needs.

¡Hola! Mi nombre es Teresa y tengo 26 años. Estudié biología marina debido a mi gran admiración por el mar y por la investigación. Hace unos años trabajando en un laboratorio empecé a dar clases a estudiantes de secundaria y descubrí otra de mis grandes pasiones, la enseñanza. Desde entonces, llevo más de 3 años dando clases particulares, tanto en academia como por cuenta propia. Estoy especializada en asignaturas de ciencias, matemáticas, física y química sobre todo, y durante mi trayectoria he trabajado con alumnos de edades muy variadas, desde los 8 hasta los 17 años, especialmente con alumnos de secundaria (ESO). Soy una persona alegre, activa y muy organizada. Me gusta conocer gente nueva y sobre todo poder ayudar a alumnos de diferentes sitios a lograr sus objetivos. Intento siempre que las clases sean amenas y siempre me suelo preparar material extra como refuerzo para ellos. En general me gusta organizar las clases según las necesidades de cada alumno. ¡Estaré encantada de ayudarte a conseguir tus objetivos!
