She has lessons as and when she needs them on topics that she chooses. George uses online aids that make the lessons as good as if he was in the room. He is calm, methodical and always listening.

"Going into my second year of economics, the maths requirements rapidly increased, and, due in part to a lack of A-level maths, I found myself struggling. Luckily, I had George to tutor me. His tutoring style was extremely effective, we would discuss beforehand what I wanted to go over, and I would send him any relevant documents from my lectures about things I was not understanding, and he would prepare explanations and worked through examples, and then we would go over similar examples together. We dealt with a wide range of mathematical problems, such as integration by parts, various methods of solving differential equations and comparative static analysis, and all of these topics were handled extremely well and taught excellently. George is punctual and shows a great deal of preparatory work before any lessons, and is then extremely effective at communicating and explaining complicated ideas. He is very knowledgeable and works extremely hard on each lesson. I would highly recommend George for anyone who needs maths help, regardless of the exact subject that you are studying." - University undergraduate,

"Great tutor! Breaks down complicated topics very well and the one-to-one sessions make the hardest subjects understandable." - University undergraduate.

Lessons are delivered in 50 minute batches. They consist of breaking down complex theoretical concepts into simplified components followed by examples and exam problems to solidify understanding of the topic. I encourage the student to explore the concepts themselves with me prompting them rather than just writing out a formulae. I focus on sharing deep mathematical insights with my student. This is a skill I refined as a PhD student. I aim to make lessons interactive and goal-oriented. I combine this with reinforcing their knowledge of theoretical concepts throughout the lesson. 

The main subjects I teach are:

- Maths and statistics KS3 to university level

- Computer science KS3 and GCSE 

- Python and SQL coding

- Data science and data engineering skills

- Maths entrance exams and competitions
