Drill until the score stops surprising you.
Timed, scenario-based practice for the Claude Certified Architect — Foundations exam.
When you are actually ready
The live exam passes at 720. We hold a higher line, because a practice score that only just clears the bar tells you nothing about a bad day.
Clear all six CP sets at 900+ / 1000
CP 1 through CP 6, sixty questions apiece. Each set has to reach 900 on its own — an average across the six does not count. Repeat a set as often as you need; only your best score is kept.
Then clear CFF at 900+ / 1000
CFF is the last gate. Save it until the six CP sets are green, so it works as a genuine dress rehearsal rather than another drill. Once it also lands above 900, book the real thing.
Everything worth reading beforehand is collected in guide_en.md.
Work through it before your first timed attempt — the sets assume you have.
