I have loved science from a young age, and I am now 20, and really enjoying studying Biosciences at Durham University. I am a firm believer that everyone can love science! I really hope that through my tutorials I can improve your understanding and encourage you to bring out your own passion for science.
I am very friendly, encouraging and patient. For over five years, I have been teaching Scottish dancing to a children’s class, and I have carried out voluntary work at a primary school over the past year. Additionally, I have experience tutoring as I have worked in a tuition centre, helping people aged 6-16 with maths, English and science work. I found this extremely rewarding; it instilled my passion to teach!
My aim is that you will find the sessions fun and enjoyable! If you’re enjoying what you are learning, you’re much more likely to remember it. I will try to make the sessions varied, and I’ll use diagrams and graphs to make complex scientific information seem much simpler.
We will cover whatever you want to cover. The session will be tailored to the topic you’re struggling with. We will build up your understanding until you’re confident you could explain it to someone else. Practicing exam-style questions is key to exam success, so after you are fully confident in your understanding of a topic, we will do plenty of these.
Am I the right tutor for you?
Please don’t hesitate to send me a message if you have any questions, or even book a ‘Meet the Tutor session’!
I studied both A Level and GCSE AQA Biology and Chemistry, GCSE AQA Maths and A Level Edexcel Maths. However, I am happy to tutor for any exam board. Please just let me know your exam board and what topic you’re struggling with when you send me a message.
I look forward to working with you!

- The action potential begins when the stimulus exceeds the threshold.
- The voltage gated sodium ion channels open.
- Sodium ions diffuse into the axon down an electrochemical gradient.
- Positive feedback occurs (more sodium ion channels open).
- This depolarises the membrane.
- The membrane potential reverses from -65mV to +40mV.
- The voltage gated potassium ion channels now open.
- Potassium ions diffuse out of the axon down an electrochemical gradient.
- The sodium ion channels close.
- Hyperpolarisation occurs.
- But the sodium potassium pump then restores the resting potential by actively transporting 3 Na+ out of the axon and 2K+ into the axon.see more
