Es una profesora muy buena.La recomiendo 100%
Raúl Guillermo Ibáñez Corrales
Sería trabajando, accesible, comprensiva y con una extensa formación en biología
María es increíble, por un lado es una persona super simpática y con mucha paciencia, si necesitas repetir las cosas 20 veces no hay ningún problema. Por otro lado sabe perfectamente de lo que está hablando, controla los temas que trata 100% y eso se agradece mucho, es una profesora muy segura de los conocimientos que transmite, la recomiendo claramente tanto si necesitas aprobar como si lo que buscas es realmente entender y comprender.
