I'm a university student studying medical science in Oxford Brookes and I have a strong understanding of Biology at A-levels/GCSE

I'm a firm believer of the worked example method. So how I usually teach people is that I will help create a strong base understanding of a simple question and then build up to other complexities within the topic the question came from. This method works great in maths based questions but it's also applicable to writing questions. I believe it's better to understand the nuances of a concept rather than memorising because it helps commit information to long term memory.
