Every candidate who passes the Claude Certified Architect – Foundations exam says the practice material was easier than the real thing. MockCerts is written to the official exam guide so it isn't: select-two items, forms drawn the way the exam draws them, the real scaled score, and fresh forms from a 420-item pool.
Each line is a complaint that appears in nearly every first-person account of the exam, and what we built instead.
From the free bank. This is the standard for all 420. Answer it.

The free tier is a real mock, not a teaser. The full bank is one payment for one exam.

Four gates before a candidate sees a question. This is the part most banks skip.
Each item targets one knowledge or skill bullet from the guide’s 30 task statements, inside one of the six published scenarios.
An independent reviewer answers every item without the key and flags anything with two defensible answers or a missing detail. Flagged items are rewritten or cut.
Answer letters are balanced and the correct option is not systematically the longest, so form gives nothing away.
Where the guide and today’s docs disagree, the key follows the guide and the explanation says what changed.
All questions are original. We never use or accept recalled exam content; using it is a violation of the exam NDA for you as well. Content-integrity statement.
We add exams where a public blueprint exists and good prep does not.
