FAQ

What is the difference between a course and a certificate?

When you complete the course requirements, including the final exam, you will get a certification of completion. Getting a certificate proves your commitment to improving your skills.

Tip: If you are confident in your skills already and have followed the free tutorials you can also enrol directly to complete the final exam for the same certification here: https://campus.w3schools.com/collections/certifications 

Our certificates are not meant to replace formal higher education but provide a cheaper, convenient way of documenting your skills. We cannot guarantee that the certifications will get you a job.
