Thanks. The affiliate that I work with offers paid content that is miles better than something could come up with over short period of time, so I'm happy referring business his way. Pouring more hours into this project isn't really worth the opportunity-cost for me at this point (consulting + bootstrapping a startup).
In my jurisdiction (Ontario, Canada), if you graduate from an accredited engineering school and gather the requisite work experience, there is no technical exam, it is the same ethics and law exam for all disciplines (PPE or Professional Practice Exam). Documenting your work experience is probably the most work-intensive task as they want you to lay out what you did and how it qualifies as engineering in great detail. Probably the biggest reason for my traffic is that I published my (anonymous) experience record, since real life examples of this document are nearly impossible to find on the web. For the exam, I basically studied for the better part of a week. It's a 3 hour exam where your answers are typically paragraphs or pages long. I get the sense that some engineers struggle with it due to language issues more than anything else.
