Version control is a method of tracking changes to code and files over time. It helps developers manage different versions, collaborate on shared codebases, identify changes, and restore previous states when needed. It is a critical tool in modern software development.

Git is a distributed version control system that enables teams to track code changes, collaborate efficiently, and manage multiple branches of development. It supports fast and flexible workflows suitable for projects of all sizes.

Branches allow developers to work on isolated changes or features without affecting the main codebase. They are essential for managing multiple streams of development and supporting collaboration between team members.

No, Git works on Windows, macOS, and Linux. While some Git operations are performed through the command line, the course supports all major operating systems and does not require prior Linux knowledge.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
