Brazilian English Student in London teaches kids and teenagers English as a foreign language

I am an 18 year old International student living in the UK. I have finished my first Undergraduate year at Durham University, hoping to graduate with BA Honours in English Literature, and I plan on spending my summer in London helping other international kids develop their level of English. Although I have little experience in tutoring kids, except for volunteer work I did during high school in Brazil, I have a high level of English, having gotten a 7.5 in my ILETS Exam and a 109 in my Cambridge English Exam and I am very good with kids. I also have a high level of technology skills, especially after having spent 2 years doing online classes, so I have learned how to better use my time on my computer when it comes to teaching and learning. Although I have a student Visa and can only work for a certain amount of hours per week, I have a flexible agenda and I am always looking for extra jobs and activities online to fill my time and help me financially, so this would be the perfect job for me.
