GCSE Maths and Physics fundamentals

Having gone through the lengthy and daunting GCSE process last year I have gained several relevant skills which I felt were very overlooked. The root cause - that I had noticed - of many students who struggled towards year 11 was a lack of understanding of the fundamentals which, had they been taught earlier, would've certainly helped them to develop their knowledge as they approached the final exam.
In my GCSEs I achieved 8 9s (A**) and 1 8 (A*) with 97% in Maths and 90% in Physics, the subjects in which I would be open to tutoring in.
