About
I built this site because I was studying for the Claude certification exams myself and couldn't find practice material that was actually checked against Anthropic's own exam guides, so I built the tool I wished existed.
Every lesson, glossary entry, and practice question on this site is written and verified by me against Anthropic's official documentation and exam blueprints - nothing here is auto-generated filler. I hold a Master's degree in AI & Machine Learning, and I maintain this project on my own, outside of any affiliation with Anthropic.
