Native level of English with extra emphasis on helping with grammar, pronounciation and everything within the English Language

An bi-lingual undergrad student who was born and raised in London with English being my first language as well as my own mother tongue being spoken. I have tutored many family members and family friends in assisting their children with matters relating to English such as exams, phrases and the context of certain words where you would use them and which alternative words work in their place. Synonyms and antonyms as an example.
