I give extra classes in different subjects: math, language, English, biology, chemistry, music... I am a 4th year biochemistry student with extensive experience in dealing with children and adolescents. I teach classes at various levels in different subjects (biology, chemistry, biochemistry, Spanish, mathematics, English, music...). I fully adapt to the needs of the student and prepare the classes according to their level of study. I have a C1 level of English. I can teach classes both in person and online, for children of different ages, and even adults.
