I'm going to be 17 years old in a week so I'm aiming for secondary students to make them feel more comfortable about GCSE

If you find is more comfortable to have a younger tutor rather than an older person teaching you. Then I'd be happy to tutor anyone. I passed science higher in GCSE with a 6-5 however biology is my strong suit and my best subject in combined science. I'm able to come up with realistic examples to help remember difficult subjects better. I'm patient and will never judge anyone on their academic ability because everyone can understand anything with a little help.
