Question about using freecodecamp

Good day, I have a question. I am new to this platform and would like to know how the courses here work. For example, all I need to do is complete 4 chapters of HTML (Basic HTML, Semantic HTML, Forms and Tables, Accessibility), do the test and I will receive a Certificate by email? I am aware that each of these chapters has a dozen or so steps to complete a given chapter. As of today, I have not started any course and I am writing about the HTML exam (coming soon). Is this how it should be? Will the exam be activated after completing all chapters and steps? I would like a clear, step-by-step explanation of how it works.

There is no announced date when the exam will be ready. It is still in development.

so after completing the courses I won’t be able to take the exam and get a certificate?

You will be able to take the exam when it is finished.

there isn’t a certificate for each chapter, there is (will be) a certificate for the full stack curriculum
