English tutor poviding lessons for GCSE and A-level students

I am 21 years old and currently studying English Literature at Univeristy so I am able to tutor both GCSE and A-level students. I got an 8 in my English Literature GCSE, a 7 in my English Language GCSE and an A in my English Literature A-level. For my GCSE I studied 'Macbeth', 'An Inspector Calls', 'Jekyll and Hyde' and the power and conflict poems meaning I am able to teach these texts in great detail. However, I have read all of the GCSE English Literature texts so I can teach them all. For my English Literature A-level, I studied 'Sense and Sensibility', 'The Bell Jar', 'Paradise Lost', 'A Doll's House' and 'Measure for Measure'. I would feel comfortable tutoring both English Literature and English Language at a GCSE level but I can only tutor English Literature at A-level.
