Scenario-Based Format & Scoring

Multiple-choice scenarios, 720/1000 to pass, no guessing penalty.

Scenario-Based Format & Scoring is a free Claude Architect lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Claude Architect learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.

What the Exam Looks Like

The exam is scenario-based multiple choice: read a realistic situation, then pick the best of 4 options where exactly 1 is correct. No code to write, no essays.

How Scoring Works

Your result is a scaled score from 100 to 1000, with the pass mark at 720. Scaling keeps different exam forms comparable — just aim well above 720 for safety.

# Scaled score range, not a raw percentage
MIN_SCORE = 100
MAX_SCORE = 1000
PASS_SCORE = 720

my_score = 760
print("PASS" if my_score >= PASS_SCORE else "FAIL")

4 of 8 Scenarios

The exam draws from 8 core scenarios, but any single sitting shows you 4 of them — and you won't know which in advance. The takeaway: study all 8.

The 8 Scenarios at a Glance

The 8 scenarios each map to a real pattern: customer support, code generation, multi-agent research, developer productivity, CI/CD, data extraction, conversational AI, and agentic tools.

No Penalty for Guessing

There's no penalty for guessing — a wrong answer costs the same as a blank: zero. So never leave one empty. Eliminate what you can, then pick the best of the rest.

# No guessing penalty -> always answer
# Expected value of guessing 1-of-4 is strictly positive
blank_value = 0
guess_value = 1 / 4  # > 0, so guessing beats leaving blank
print("Answer every question:", guess_value > blank_value)

Who the Exam Is For

The audience is solution architects with 6+ months of production Claude experience. That's why questions are scenario-based — they test the judgment that comes from shipping, not memorized facts.

The 5 Domains and Their Weights

Questions spread across 5 weighted domains: D1 27%, D2 18%, D3 20%, D4 20%, D5 15%. D1 carries the most weight, so agent design and orchestration deserve the deepest study.

DOMAIN_WEIGHTS = {
    "D1 Agent Architecture & Orchestration": 27,
    "D2 Tool Design & MCP": 18,
    "D3 Claude Code Config & Workflows": 20,
    "D4 Prompt Engineering & Structured Output": 20,
    "D5 Context Management & Reliability": 15,
}
print(sum(DOMAIN_WEIGHTS.values()))  # 100

Why Scenarios Beat Trivia

A trivia question asks what stop_reason returns; a scenario drops you mid-loop and asks what to do next. You're given a real situation and must choose the architecturally correct response.

Distractors Are Often Anti-Patterns

Wrong options are written to be tempting — many are classic anti-patterns: parsing text for 'done', iteration caps as the main stop, or enforcing rules with prompts not hooks. Spot one, rule it out.

Read for the Strongest Answer

Often more than one option is technically valid; the exam wants the strongest for the context. Anchor on principles: terminate on stop_reason, use hooks for critical rules, pass context to subagents.

# Correct agentic-loop termination: driven by stop_reason
while True:
    resp = client.messages.create(model=MODEL, max_tokens=1024,
                                  messages=history, tools=tools)
    if resp.stop_reason == "tool_use":
        history.append({"role": "assistant", "content": resp.content})
        history.append(run_tools(resp))   # append results, continue
        continue
    break  # end_turn / max_tokens / stop_sequence -> stop here

A Smart Test-Taking Strategy

A smart strategy: answer everything, eliminate anti-patterns to shrink 4 options to 2, weight prep toward D1, study all 8 scenarios, and aim past 720 with margin.
