I want to take to the exam of the Magento 2 Professional Developer Certification. I am Finding Study Materials for Preparing Exam. Magento Take Fee $260 for Exam and Certificat. I have one Question that they will Provide me any video tutorials or any Special books for Preparing Exam and Easy way to understand the flow and structure of Magento.
The short answer is no.
There are resources out there
I can only reiterate what someone else has said. I'd be wary of this certification. You will gain more by putting together magento builds.
