How to enroll in "Penetration Testing Specialist" properly?

I wanted to try to get the “Penetration Testing Specialist” certificate and I went to the “Penetration Testing Specialist” page, I clicked on the “Get Started” button, Now I can see the “Penetration Tester” path on my dashboard.

But as of now, I didn’t pay anything for it. (They mentioned that it cost $490).

I think I’m not enrolling properly.

please advise me.

It’s free to enrol into the certificate but each module costs some cubes. Cubes can be gained for free through completing other modules. But with the amount of cubes the certificate training costs it’s more feasible to buy the cubes for the modules.

Nice, So we pay as we go. When we complete the 28th module, should we pay some for taking the exam for the cert or the exam will be free when we pay & complete all 28 modules?
