GCSE Maths tutor confident in teaching grade 4 and above topics

I have a PhD in microbiology, a BSc in Biochemistry, grade A in A-level maths, A* in GCSE maths, and I have previous experience with maths tutoring. I love maths and have pursued further education in maths. I'm passionate about providing a different or unique perspective to facilitate maths learning. I am confident in teaching students that are looking to achieve their pass grade C or looking to achieve higher grades of B and above. I particularly enjoy calculus and algebra, but I am confident in teaching any topics that you might need assistance with.
