Work through the lessons in order. Each one ends with exercises you can do in your own office and a few short questions to check yourself. Answer the check and the lesson is recorded as done, in this browser, with no account involved.
Finish every lesson and you can print a completion record for this course. The course also counts toward the certifications, which are the larger thing: several courses plus a timed comprehensive exam, ending in a certificate whose reference code anyone can verify.
