George

I am a full-time tutor with over ten years of teaching experience.

Academic background:
Sussex University - PhD Hirschfeld scholar; pass with minor corrections
Sussex University - 1st class honours MMath degree

I`ve spent 6 years working in the data tech industry. I applied math and technical skills to solve data problems and conduct technical training for work colleagues. I worked closely with data engineering technologies, including Python and SQL.

What to Expect From Lessons:
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 students to explore the ideas themselves, with me prompting them rather than just writing out formulae (I view myself as a study aide). I focus on sharing deep mathematical insights with my students, a skill I refined as a PhD student.
I aim to make lessons interactive, supportive, collaborative, optimistic and goal-oriented.
I combine this with reinforcing their knowledge of theoretical concepts throughout the lesson.

Session Admin:
- Students are required to bring pen, paper, and calculator to sessions.
- Sessions last 50 minutes in a one hour slot with the remaining 10 minutes used for answering remaining questions, exporting the whiteboard, and booking future sessions. This time may be split at different times.
- Please provide at least 24 hours` notice for any topic requests or changes agreed in the previous session.
- Resources from the student must be sent at least 24 hours before the scheduled session.
- Solutions are sent to problems the student would like me to review with them must be provided in advance.
- sessions cancelled within 24 hours of the scheduled time will incur a 50% cancellation fee.
- The full session fee is charged if a student does not attend a booked session without prior notice. I will remain in the session for 15 minutes after the scheduled start time before it`s considered a no-show.
- One-off session availability is allocated on a first-come first-serve basis.
- Homework tasks are set based on gaps in the knowledge of the student observed during sessions. They`re a mixture of tasks from answering open-source problems, understanding definitions, memorising formulae, or research tasks. The homework is to be completed at a pace the student feels comfortable with. However, if the homework list gets too large, session time will be used to reduce the list of tasks.
- One-off session booking requests are accepted maximum 2 weeks in advance.
- Regular sessions must be honoured or cancelled in advance. Missed regular sessions without prior notice will result in the slot being released to another student.
- Additional sessions are offered to any of my students based on my current availability upon request.
- My working hours are between 8am and 11pm UK time. I accepted session requests during these times based on availability.
- I take holidays throughout the year. I will provide notice to my students when these are approaching. I will offer session slots before or after the break to students if they wish to make up for any lost time.
- I discourage the use of calculators and encourage their use only when necessary.

I also deliver group lessons. Please enquire if interested.

The main subjects I teach are:
Maths and statistics KS3 to university level
