Exam Strategy — How to Approach the CCA Exam

THE ANALOGY

A surgeon walking into the operating room. They've done the preparation. They know the procedure. They've reviewed the specific case. Now it's not about learning — it's about execution: read carefully, apply what you know, trust your preparation, don't second-guess.

⚠️ EXAM TRAP — The Wrong Answer People Choose

Changing answers based on second-guessing. The exam is designed so your first well-reasoned answer is usually correct. Changing answers based on uncertainty (not new insight) is statistically worse.

KEY POINTS

1 Format: 60 questions, 120 minutes, 4 scenarios randomly selected from 6, passing = 720/1000.

2 Time management: 2 minutes per question maximum. Flag and move on if stuck. Return to flagged questions.

3 Question strategy: read the scenario setup, identify which domain(s) are being tested, apply the principle.

4 Two-right-answers: identify the signal word, match to principle, select the architecturally superior option.

5 Anti-patterns: longest answer is not always right. Most complex is not always right. 'It depends' is not a CCA answer.

6 Exam day preparation: the night before — review the 10 most-tested concepts, not new material.

Exam Structure

Total:        60 questions
Time:         120 minutes
Per question: 2 minutes average
Passing:      720/1000 (72%)
Format:       Multiple choice, 4 options each
Scenarios:    4 of 6 randomly selected

Questions per scenario: ~15 per scenario × 4 scenarios = 60
(some scenarios may get more or fewer questions)

The 2-Minute Question Process

Step 1: Read the scenario setup (15 seconds)
  What is being built? (customer support, code review, extraction?)
  What is the problem? (reliability, compliance, performance?)

Step 2: Identify the domain(s) being tested (15 seconds)
  Compliance enforcement → D1 hooks
  Tool selection → D2 descriptions
  CI/CD → D3
  Structured output → D4
  Error handling → D5
  
Step 3: Read all 4 options (20 seconds)
  Don't stop at the first plausible option

Step 4: Eliminate clearly wrong options (20 seconds)
  Usually 2 options are obviously wrong

Step 5: Apply the principle to the remaining 2 (30 seconds)
  What does the scenario signal? ("must always" → determinism)
  Which option embodies the correct principle?

Step 6: Answer and flag if uncertain (5 seconds)
  If confident: answer and move on
  If uncertain: guess best option, flag for review, move on

The 10 Most-Tested Concepts — Know These Cold

1. stop_reason drives loop control — never text parsing
2. Programmatic enforcement (hooks) vs prompt guidance
3. tool_choice: auto vs any vs forced — and when each applies
4. Minimal footprint — request only necessary permissions
5. Hub-and-spoke — coordinator is the only communication hub
6. CLAUDE.md hierarchy — user (not git) vs project (git) vs directory
7. -p flag required for CI/CD headless execution
8. JSON schema eliminates syntax errors, not semantic errors
9. Multi-instance review — independent instance, no shared context
10. Batch API — 50% cost, up to 24h, never for latency-sensitive work

60-Second Process for Uncertain Questions

You've eliminated 2 options. Two remain. You're not sure.

Step 1 (15 sec): Re-read the scenario for signal words
  "must always" → determinism → enforcement
  "compliance" → programmatic
  "independent" → parallelize
  "performance" → parallel execution
  "files changed" → fresh session

Step 2 (15 sec): Apply the signal word to the two options
  Which option embodies the signaled principle?

Step 3 (15 sec): Trust your first instinct
  Your prepared knowledge is more reliable than exam-pressure reasoning
  If no signal word helped: go with your gut and move on

Step 4 (15 sec): Flag and move
  Mark for review. Time-box at 2 minutes. Move to the next question.
  You can return to flagged questions if time permits.

Night Before — What to Review

DO review:
- The 10 most-tested concepts above (5 minutes each)
- The six scenario domain maps
- The two-right-answers pattern library

DO NOT:
- Read new material
- Try to learn anything you don't already understand
- Practice more questions after 9pm

DO:
- Sleep adequately — cognitive performance matters more than cramming
- Eat well before the exam
- Arrive/log in 15 minutes early

Passing Score Reality

720/1000 = 72% = 43-44 of 60 questions correct

You can get 16-17 questions WRONG and still pass.

This is not a perfection test. It's a mastery test.
If you've studied all 6 domains thoroughly, you know enough to pass.

Key Takeaways

2 minutes per question maximum — flag and move on if stuck
Signal words → principles → answers — don’t analyze, pattern-match
Know the 10 most-tested concepts cold — review the night before
720/1000 passing — you can miss 16-17 questions and still pass
Sleep — cognitive performance matters more than last-minute cramming
