Prepare for the GitHub Certified: Agentic AI Developer (GH-600) certification with realistic practice tests built around GitHub Copilot, secure automation and production-ready agentic development workflows.
This Harbourmetric course includes five full practice tests, Sets A–E, plus one advanced Final Mastery Test. The course also features four integrated case studies, giving you practical experience analysing complete environments, technical requirements, workflow configurations and security constraints.
What’s Included
- 5 complete GH-600 practice tests — Sets A to E
- 1 high-difficulty Final Mastery Test
- 4 realistic case studies
- GitHub Copilot and agentic development scenarios
- GitHub Actions, YAML and repository-governance challenges
- Secure workflow design and troubleshooting questions
- Detailed explanations for every correct answer
- Clear feedback explaining why the other options are incorrect
- Performance tracking and a course leaderboard
- Unlimited opportunities to repeat and improve
Realistic Agentic Development Practice
Sets A–E test your ability to configure, secure, troubleshoot and evaluate agentic development workflows across realistic GitHub environments.
You will work through questions involving:
- GitHub Copilot and Copilot coding agent
- GitHub Copilot CLI
- Agent planning, memory and state management
- Context drift and error analysis
- Evaluation signals and quality improvement
- Issue-to-pull-request workflows
- Draft pull requests and human review
- GitHub Actions and reusable YAML workflows
- Required checks and branch protection
- CODEOWNERS and repository rulesets
- Workflow identities and permissions
- Least-privilege access
- Guardrails and human approval gates
- Protected environments
- Secure agent and workflow execution
These are not simple memorisation questions. You will analyse practical development situations and select the approach that best balances automation, security, reliability, governance and developer productivity.
Integrated Case Studies
The four case studies require you to review business requirements, technical constraints, existing configurations, workflow files, logs and planned changes before selecting the correct GitHub or Copilot solution.
You may need to identify a failed workflow, secure an agent’s permissions, enforce approval requirements, improve evaluation results or design an end-to-end issue-to-PR process.
Final Mastery Test
Complete your preparation with a demanding Final Mastery Test covering the full GH-600 topic scope.
This capstone assessment combines GitHub Copilot, agent planning, repository governance, workflow automation, security controls and troubleshooting within complex scenarios requiring practical judgement and multi-step reasoning.
Learn From Every Decision
Every question includes detailed feedback explaining:
- Why the correct approach is the best solution
- Why each alternative fails to meet the requirements
- Which GitHub or Copilot capability is being tested
- How similar workflows and security controls differ
- How decisions affect safety, reliability and maintainability
- How to avoid common exam traps and insecure configurations
This explanation-first approach helps you build practical agentic development judgement instead of memorising isolated features.
Track Your Progress
Monitor your results, repeat assessments and compare your performance through the Harbourmetric leaderboard.
Use each attempt to identify weaker areas, review the explanations and improve your decision-making. Achieving 80% or higher consistently across multiple assessments is a strong indication that you have developed the knowledge and exam technique required for certification day.
Prepare with realistic GitHub agentic development challenges, learn from every answer and build the confidence required to pass the GH-600 exam.
