Exams and Certifications

I purchased the 3DEXPERIENCE ENGINEER for Students (comes with 4 exams for certifications)

and the SOLIDWORKS Cloud Apps for Students (comes with 2 exam for certifications).

However, every time I click on the certification to take it, it tells me I need to pay again.

Is there somewhere I need to go that has all my exams and certifications?

I would please like to know where the 6 exams are, is there a specific website that has all of them??? Does anyone know???!!!???

 

I have tried here:
