Hello, I'm Hannah, I'm a first year Biology undergraduate at Durham university. I am here to share my knowledge and enthusiam in Biology for anyone who needs some support.
Last year I volunteered in India, teaching my own class of six year olds for a month. I also have experience working in a senior classroom, working one-to-one with pupils. I am considering a career as a teacher and feel tutoring will develop my passion for education.
Before each session I will ask you what topic(s) you would like to focus on, then I can prepare and structure the hour so that your time is used wisely and is as productive as possible! I will need to know what exam board is being used so that the sessions are tailored specifically to that. I can help you understand new concepts, find revision techniques that works best for you and work through exam questions.
Biology really is fascinating, although it can be quite content heavy. By using lots of diagrams, mind maps and flow charts, learning can be made easy and fun! I aim to make sessions really interactive and enjoyable.
I hope you feel I will be able to help, do go ahead and book a 'Meet-the-Tutor-Sesison' where I can answer any questions you may have. I will try to accomodate times that suit you best, your sessions are a priority!
Looking forward to meeting you,

The myelin sheath is a fatty layer made up of the hugely expanded plasma membrane of schwann cells which surround the axon of neurons. The axon is unprotected where the sheath of one cell meets the next and these points are known as nodes of Ranvier. Voltage gated sodium ion channels are confined to the nodes. The influx of sodium ions at one node creates enough depolarization to reach the threshold of the next. This means that the action potential 'jumps' from one node to the next. The process is known as saltatory conduction and results in much faster propagation of the nerve impulse compared to non-myelinated neurons (where action potentials travel as one slow wave)see more
