Preparing for Claude Certified Architect? An open-source kit with 90 practice items

Alexioc · reddit · 2026-08-16

To prepare for the CCAR-F (Claude Certified Architect, Foundations) exam, the author built an open-source toolkit containing 30 task statements, 5 domains, 98 linked wiki notes, and 90 original practice items.

Core Feature: Diagnostic Report

Instead of simple scoring, the tool analyzes the "distractor families" of wrong answers and ranks them by rate (error frequency / availability of that option), revealing cognitive blind spots. For instance, it might show a tendency to solve configuration problems via prompts.

Technical Highlights:

Every option (including correct ones) includes an explanation of why it is right or wrong.
Provides percent-correct scores by domain (e.g., identifying a weak Domain 2) and lists missed task statements with specific fix commands.
Deliberately avoids outputting scaled scores to prevent false confidence and focus on weak areas.

Disclaimer:

Unofficial tool containing no actual exam content. All items are original, written from published objectives. The author is also an exam candidate.
