Articles

I write here when something is worth saying about cert prep beyond the basics. Each article goes deep on one idea, what AI cert prep actually is, how adaptive testing changes a study plan, why certain prep mistakes cost weeks of work.

If you're new to all of this, start with a free CAT evaluation on ClaudeLab, five minutes, twenty-five questions, you see exactly where you stand on your target cert. The articles below give you the why behind the how.

If you arrived here from a search and want the product overview before reading articles:

Why these articles exist​

Most cert prep content is written to rank, not to help. I try to do the opposite. Each piece is something I would have wanted to read before sitting an exam, specific, honest, and short enough to finish before your coffee gets cold. Read them, push back, email me what's missing.
