Hola! Mi nombre es Cecilia, soy Bioquímica egresada de la Universidad de Buenos Aires. Durante mis años de facultad me dediqué a dar clases particulares de Química a alumnos de nivel secundario y universitario. Luego me dediqué también a otras áreas de mi profesión pero siempre seguí manteniendo algunas clases porque me gusta mucho enseñar. Me encantaría ayudarte con aquello que te está costando aprender!! Si quieres, concertamos una entrevista, así nos conocemos, charlamos de los contenidos que necesitas aprender y te cuento cómo diagramaremos las clases! Un saludo!!
