Lived in the United Kingdom for 19 years and was born and raised in London

I have lived in the United Kingdom in London for 19 years and was born and raised in the borough of Lewisham. I went to primary school, secondary school, and sixth form in London and currently studying at university in Brighton. For GCSE English Language I achieved a grade 7 which is equivalent to an A. All the schools that I have attended in the past have been British schools which were all multicultural with people coming from different backgrounds.
