BIOMEDICAL ENGINEERING STUDENT WITH CPE TEACHES ENGLISH

I'm a 21-year old biomedical engineering student in university Carlos III in Madrid, almost in the fourth year. I've got all the Cambridge certificates from PET (Preliminary English test) to CPE (Certificate in proficiency English, C1). I studied at a bilingüal school (International Montessori School Parque Conde de Orgaz, started there when I was 2). There, besides being adressed to in English the whole time, I also learnt French (B2 level). I've worked as an activity leader for three summers in English immersion camps  with kids aging 14-17. I offer English classes adressed at kids or teenagers during the summer, in the afternoons from 5 pm onwards. Preferably, Ciudad Lineal- Suanzes neighbourhood but I wouldn't mind taking public transport somewhere near. 12 euros /hour.
