Time Management

With 1 minute and 51 seconds per question, pace yourself from the start. Don't spend more than three minutes on any single question during your first pass.

Reading Questions Carefully

Practice tests are the most reliable predictor of exam readiness. Each practice test here follows the real GitHub Copilot exam format: 65 questions, 120-minute time limit, and questions distributed across all 7 domains according to the official exam weights.

Use your scores by domain to identify weak areas, study those areas, then test again. Aim to consistently score above 80% on practice tests before scheduling your real exam.
