I have added in a CPF 101 page today. Generally, having a 101 means that beginners new to the CPF can get up to speed on current CPF policies. The 101 guide aims to keep it simple and logical, illustrating all the basic principles and concepts.
Currently, it only covers the Introduction and Retirement scheme. I hope to cover also the Housing scheme, Healthcare scheme, Education scheme, Investment scheme in the near future. Though by covering all, it might be as thick as a book.
By making it clear on 1 site, it should allow you to understand without the need to flip back and forth pages on Q&As at the current CPF website or hunt for answers in other blogs.
Do let me know if there errors or feedback to the CPF 101 guide. It shall constantly be approved over time for clarity and accuracy.
