The Zero to GP content is currently in production. The currently site content is limited.
Zero to GP covers the core facts and guidelines you need for exams. It is impossible to cover 100% of everything that could come up in any medical exam. Even if it did cover 100% of everything, you would not have enough time to learn it all.
Instead, Zero to GP aims to eventually cover the core 80-90% of content that could come up in exams and does so in a way that allows you to quickly understand, learn and store that information in your memory.
