GitHub Copilot GH-300: 420 Practice Questions

This course contains the use of artificial intelligence.

A Copilot answer can look convincing while using the wrong API, missing a requirement, or relying on a control that does not apply to the current workflow. Prepare for GH-300 by practicing the decisions behind these situations: what context to supply, which feature to use, what a test actually proves, and how to interpret policy and exclusion boundaries.

420 original English practice questions are organized into six tests. Four topic sets let you focus on weak areas; two mixed practice exams each contain 60 questions and allow 100 minutes. The mixed sets follow the six domain-weight ranges in the GitHub Copilot study guide effective August 7, 2026. Their question count is a training design, not a claim about the official exam's fixed length.

Choose your starting point

• AI responsibility, data flow and model limits: 80 questions.
• Copilot features across IDE, CLI and GitHub workflows: 100 questions.
• Prompt engineering, development and verification: 80 questions.
• Privacy, content exclusions and safeguards: 40 questions.
• Two mixed practice exams: 60 questions each, 100 minutes per attempt.

Learn from each decision

Every question includes feedback for each option, an explanation of the deciding conditions, and a study tip. Scenarios cover prompt and tool boundaries, generated-code behavior, unit and integration evidence, synthetic test data, performance trade-offs, and the scope of privacy controls. Some questions ask you to inspect small Python, SQL, configuration or command examples.

Current product behavior matters. This course distinguishes the standalone Copilot CLI from older examples, addresses prompt files and agent workflows with their applicable harness constraints, and treats Spark retirement as a dated product change. Where official product documents differ on a control's scope, questions keep the applicable conditions explicit instead of treating every surface as equivalent.

Use the tests deliberately

1. Work through a topic set and record why you chose each answer.
2. Review every option's feedback, including questions you answered correctly.
3. Use the study tips to revisit the relevant concept and practice in your own permitted environment.
4. Complete the mixed exams without notes, then return to the topic sets for weak areas.

The 70% practice threshold is a study setting; it is not a conversion to the official scaled passing score. These are practice tests with written explanations, rather than video lessons or a hosted lab environment. A Copilot subscription is not needed to attempt the questions, although hands-on experience can help you connect the scenarios to your work.
