I am a native British English teacher with over 200 students in Madrid. I have proofread work from all ages and levels. I also work as a bilingual assistant in a school in Madrid. I started my business in 2009, qualified to teach English as a second language as well as 8 other diplomas. I have a B1 Spanish level. PS...I think it really helps that I love English!! I have worked with students to prepare them for Cambridge exams up to level C2, requiring the highest levels of spelling, grammar and punctuation. I have proofread university dissertations, medical slides and content writing based on Tarot cards. Any subject I am not familiar with I will research.
