I have the "3DExperience Engineer for Students" license package, and already previously obtained the "3DExperience Mechanical Designer for Students - Associate" digital badge certification by complete its exam. Now that I've completed the "Practice SIMULIA Linear Structural Validation" learning modules, I'm ready to take the exam to obtain the "3DExperience Structural Designer - Associate" certification.

This is the link to the exam:

However, when I try clicking on the "Enroll now" button, it prompts an enrollment fee of "2 credits", which I apparently do not possess. If I could previously take the "3DExperience Mechanical Designer for Students - Associate" exam, why am I unable to take this exam? The screenshot of the problem is shown below:

How can I purchase the "Credits" necessary to enroll in certification exams?

My questions are: 

- Is there a webpage or any 3ds platform that consolidates all certification courses for ease of access? 

- For certifications that require "credits" to enroll, how can I purchase these "credits"?

Any help or insight will be greatly appreciated, thanks a lot!
