I will tutor any subject and age level where I am confident I can meaningfully improve the client's understanding. Over the years this has ranged from practising English language with 7-year-olds to helping final year university students with their Engineering Science dissertation. So I am something of a Swiss-army tutor!
However, the areas I cover are mainly as per the subjects and age ranges listed below:
Maths: ages 7 to 18, plus university-level support (upon request)
Physics: ages 10 to 18
Science (combined or physics/chemistry/biology): ages 10 to 14
English & Reasoning (verbal/non-verbal): ages 10 to 14
In the subjects listed above I have experience in tutoring a wide range of exam boards (e.g. Edexcel, OCR, AQA), as well as IB.
