Patient and thorough tutor for A level/GCSE physics students

I have a master's degree in Data Intensive Astrophysics from Cardiff University, with experience tutoring an introductory programming module during my master's. I am open to adapting my tutoring approach, whether the focus is more on understanding the core material or on how to answer exam-based questions, or a mixture of the above.

I am also willing to do in-person tutoring for students in the Cardiff area.
