I am an undergraduate student in Environmental Technology Engineering at the Polytechnic University of Madrid. I hold an International Baccalaureate certificate specializing in Technology. I have certified my studies at level C1. I can teach both at home and online, with no travel restrictions. Group classes are also available. I base my teaching methodology on the student, personalized to each case and structured around the subject matter, although there are always overlaps between different subjects. The class will be dynamic, based on teaching and learning, not on rote memorization and repetition throughout an academic career, but on mastering the different skills.

I am a second year Biology student at the Rey Juan Carlos University.
I offer classes of common subjects at school levels such as ESO and Baccalaureate.
These courses will be adapted to the needs and rhythms of each student, the main objective being that they reinforce their knowledge of the subject without overloading themselves. In addition to exam preparation.
