I am a hardworking and driven undergraduate student from the UK, majoring in history at the University of St Andrews.
I have tutored for several years. When I graduated high school, I began helping younger students from my school prepare for GCSE and A Level examinations, particularly in History, French, English Literature and Maths (which were my own A Level subjects). I also undertook some tutoring at university, helping students in lower years with classes I had already sat and leading revision groups. Last year, I tutored online for several months before stopping to focus on my dissertation preparation.
I aim to not only pass on facts to my students, but also to teach transferable skills such as structuring arguments, analysing sources and supporting points with evidence. These skills help with essay writing and help to prepare students for further education in the future, such as university, and are crucial for overall academic development.
