About me


    I am a final year medical student at Nottingham and I like to take a friendly relaxed approach to both being a student and a teacher. I am easy going and very passionate about both teaching and science...but that does not make me particularly unique on this website. So why me? What would I offer you that is different? 

   Well whether it is final year medical school exams or GCSE biology exams I have always believed that you can get good marks by regurgitating facts but you can get great marks by doing two things. First is learning the underlying scientific mechanisms and learning things from first principles so you properly understand the science. The second is developing a good exam technique and knowing which boxes to tick and which trigger words to use in your answers.

   I will do my best to help you with these things. This has been my exam strategy for 7 years so I have lots of tips and hints to be able to help you.  I have experience teaching physiology to second year medical students using this exact strategy and received extremely positive feedback. Learning the mechanisms turns science from a series of unrelated facts, to a unified picture that will make sense. Armed with a proper scientific understanding and good exam technique I will help you get those A's and A*'s.


   Everybody learns differently and after getting to know you I will tailor my sessions to your strengths. If you are a visual learner, diagrams and colours it is, if you are more into mnemonics then I have plenty of those from med school. The overall format will be part 1 : learning and understanding the topic, and part 2 : how to write an A* style answer on that topic (we all have to learn to jump through the exam hoops).


Of course! I know what a headache that can be and I have done numerous mock interviews with potential candidates before and will be able to offer you lots of advice about things like UCAS, the personal statement and most importantly those daunting medschool interviews (which aren't all that bad when it comes to it I promise!) I know what it is like to be terrified at the prospect of medschool applications believe me, but a few pieces of structured advice and some confidence building which I am more than happy to give can really make a huge difference in an interview.

This can be a very stressful time and having someone to talk to and get advice from can make a world of difference. If you are interested drop me an email or book a session !

   Cystic Fibrosis is a genetic condition that results from defective chloride ion channels. Normally a protein known as the “Cystic Fibrosis Transmembrane conductance Regulator” (CFTR) transports chloride ions across the cell membrane and out of the cell. This movement of Cl- ions out of the cell causes Sodium ions to also move out of the cell due to the electrostatic attractions between the Cl- and Na+ ions. The increased levels of Na+ and Cl- outside of the cell mean that the fluid outside the cell has a higher concentration of solute (IE there is a higher concentration of water molecules on the inside of the cell.) This causes water to move by osmosis out of the cell. In the cells lining the airways, These Chloride ion channels help to pump chloride and therefore sodium and water out of the cell into the surrounding mucus (which is also produced by the cells lining the airways.) This osmotic movement of water makes the mucous more watery and less viscous. In Cystic Fibrosis a mutation in the genes coding for the CFTR protein means that the ion channel is defective and cannot pump chloride ions out of the cell. This means that sodium and therefore water cannot be added to the extracellular mucus lining the airways making it very thick and sticky. This excessively viscous mucous damages the cilia (small hairs) lining the airways. The cilia cannot properly clear mucous (which contains trapped pathogens) from the airways, meaning that those pathogens linger in the airways and are more likely to enter the respiratory tract and lungs. This results in recurrent chest infections.
