I am a post-graduate veterinary student in my fourth year at Bristol Univeristy. I graduated from Bristol in 2013 with a First Class Honours in Biological Sciences before starting another degree in Veterinary Sciences so it is clear that I love science!
I am a very approachable, friendly, dependable person who thoroughly enjoys teaching.
These sessions are all about you so you can guide what we cover. If a topic seems too complex and overwhelming we can split it up into smaller sections and take it one step at a time. I like using diagrams, mind maps, quiz questions etc in my teaching - whatever works for you; my main aim is to make the sessions fun and engaging!
Please get in touch if you have any questions. Just let me know your exam board and the particular areas that you find difficult.
Hopefully hear from you soon!

The heart muscle is myogenic and initiates a heartbeat through an electrical conduction system; both the sinoatrial node and atrio-ventricular node are essential in this mechanism.
The sinoatrial node (SAN) is a region of cardiac fibres located in the right atrium. The electrical wave of stimulation is initiated here and extends over the two atria, causing them to contract. It is often referred to as the pacemaker of the heart.
The atrioventricular node is a region of cardiac fibres located between the two atria. The electrical stimulation, initiated in the SAN, is transferred through this region to the ventricles.
(The excitation then passes down the Bundle of His, into branching Purkinje fibres, before reaching the ventricle walls and causing them to contract)see more
