I have just downloaded and read the course material and can not locate the exam password.

The password (referred to as code word in some courses) will be boldly shown somewhere within the course PDF. There should be a big orange star followed by the phrase: "Please remember the word "PASSWORD". You will be required to enter it in order to proceed with the online examination". The password specific to a particular course will be between the quotes (like the above "PASSWORD"). The easiest way to find this after you've completed the course is to search the PDF. To do this, just hit the ESC (Escape) key while in full-screen mode, then press "F8" to restore the window's toolbar. You will then be able to access the Find/Search tool. Just search for the word "word", and the page with the code word will show up in the results. If you still cannot find the password, please drop us an email (including the course name) at info@aecdaily.com.

The term "Fresh Water" in slide #8 seems odd - shouldn't this be "total water" Fresh water, in my usage, would be non-salt water. AM I missing something?

Thank you for drawing this to our attention. We have updated the course.
