First of let me ask this, would you trust someone with low credit for a loan? no, not really right? well certification exams are more of a stamenet saying "hey! this person knows enough about the topic, he passed"

as for the tests questions, they're made up by multiple people whom were hand picked due to their real life experience.

Secondly, if people thought jumping of a bridge was fun, would you? studying for certifications isn't easy, nor is it a joke, with over 10 different certifications and 10 years experience teaching IT and working in the field at various levels, i still get nerous when taking updates.
