Zero to Finals 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 Finals aims to cover the core 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.
Some topics are not yet covered by Zero to Finals (e.g., O&G, dermatology, data interpretation and statistics). There are plans to add resources for all of these topics in the near future.
