My name’s AD and I’m a 3rd year medical student at Bristol tutoring Chemistry & Biology.
I worked hard at my A-levels and didn’t always find them easy, which enables me to understand the frustration of trying to process difficult concepts. My teaching style is approachable, clear and concise; having worked with a wide variety of abilities before, I know that different learning styles calls for varying teaching methods. I work with my students to set clear goals and aims and tasks to do during the week to solidify knowledge to monitor progress and quickly gain a strong sense of success.
I know that exam technique is often as important to crack as syllabus content so I like to focus my lessons on exam questions to give students the confidence and technique needed to perform to their best under exam conditions.
I have also provided a personal tutoring service for a medical school applicant, which included helping to time manage, personal statement work, UKCAT help and interview prep. I am delighted to say he is happy at St George's, having just started this academic year.
So whether you’re looking for a crash course before a big test or consistent help through out the academic year, I’m free most weekday evenings and weekends, so just get in touch!

Just to some basics:
Gas exchange of carbon dioxide and oxygen occurs in the alveoli, small sac shaped branches of the lungs, grouped together similarly to grapes. When you breathe in, oxygen from the inhaled air diffuses through the walls of the alveoli into next door capillaries. Cells in the body produce carbon dioxide as they respire, which returns to the lungs to leave the body.
Back to the question:
To maximise this gas exchange - alveoli have a large surface area to volume ratio, to maximise rate of diffusion. They have walls that are extremely thin (one cell thick) so that the gases can diffuse quickly through the alveoli wall to the capillary or visa versa. Alveoli are lined in fluid to allow the gases to dissolve faster. Alveoli are surrounded by capillaries to maximise the surface area in which the gases can diffuse.
