Science graduate teaches science at all levels but mainly focuses on GCSE and A level content

I have an undergraduate degree in Marine Science and have been tutoring remotely for three years. I primarily focus on biology, chemistry and physics at a GCSE level but I am happy to tutor older or younger students that may require additional help. I am most familiar with the AQA and Edexcel exam boards and have created material based on their requirements, however, I am willing to look into other exam boards if necessary.
