Degree: Biology (Bachelors) - Bristol University
I'm currently in my second year studying Biology at Bristol University. I'm enthusiastic about my subject and science in general and would love to help others to love it as much as I do!
I have been successfully mentoring students for the past academic year, and have found it both productive and enjoyable! I love being able to help students reach the grade they desire and deserve. I have also run a pastoral mentoring scheme so I hope that I'll create a friendly atmosphere for tutoring sessions to help you learn best.
What I can help with:
As well as enabling you to understand the theory behind your subject I feel that in order to achieve top grades exam technique is just as important as even if you know the facts inside out, if you can't get your thoughts onto the answer sheet they are of no use to you whatsoever!
I encourage you to lead the sessions - highlighting anything you're unsure or concerned about. I'll explain the topic as best I can, using the interactive whiteboard and fun memory tricks and analogies where I can, until you know it so well you can explain it to me. I am also happy to test you when exams draw near and mark questions objectively.
A daunting process for anyone - how are you meant to convince several universities, possibly for different subjects, to accept you in about a page?! I, thankfully, got accepted into every university I applied to including Imperial and UCL, therefore hopefully I am able to give some guidance and friendly advice on what might make you rise to the top of the pile - and make the whole process less terrifying!
If you have any questions or are unsure, please send me a message or book a free 'Meet the Tutor' session for more information.
In any queries please let me know what subject you're interested in, which exam board you're using and if there are any specific areas you need help with! Thanks, and I look forward to meeting you!

A constructive plate margin can also be called a divergent plate margin, and it is where two tectonic plates move in opposite directions away from one another. Magma rises up between the plates forming new crust (hence constructive plate margin).
Volcanos are common here due to the rising magma, and earthquakes can occur but they are generally minor.see more
At rest, the potential difference between the inside and outside of the neuron is around -70mV. The sodium potassium pump is continually pumping 3 Na+ ions out for every 2 K+ ions it pumps in, and this maintains the resting potential of -70mV.
During an action potential a few sodium ion channels open, and Na+ diffuses into the neuron, decreasing the value of the potential difference. If and when the potential difference reaches the threshold potential of -50mV voltage-gated sodium ion channels open and the neurone is depolarised reaching a maximum potential difference of +40mV.
At this point the sodium ion channels close and potassium ion channels open allowing K+ ions to diffuse out of the neuron which is repolarised to -70mV. Generally this target is overshot (hyperpolarisation) to about -90mV, but the sodium-potassium pump corrects this.see more
