Marketo Expert Certification Really?

Hello,

Confused by the fact that it seems like the only way to get certified is by purchasing a $45 camera and taking Kryterion’s Online Proctoring (OLP) service (costing an additional $175).

For those of you who are certified, is this really the only way to get certified?  No approved testing sites?  I'm SFDC certified and that was super easy as I was able to go to a exam center near my home.

Thank you!

Kyle
