General Instructions

The reading courses include reading material in the form of PDF.

After you have read the course reading material, there is an exam based on the reading material. You may access the reading material while you are answering the questions. You have the option of skipping around and don’t necessarily have to answer all of the questions in the order they are presented, but questions which remain unanswered when you push the button “Submit all and finish” will be marked as incorrect.

In order to complete the course and receive the certificate of completion, you must pass the exam with a score of 75% or better. Once you have done this, you will be able to pint out your certificate or download it. The certificate has a reference number that can be used for reporting your CE to the appropriate governing body or organizations.

Taking a course and getting the certificate

You get a total of 3 attempts at the exam.

Logging out and logging in again is not considered completing an attempt. Your work is automatically saved each time you click to the next question. You can go back and change your answer anytime before you finish the exam. You will have a chance to review your answers. An attempt is completed when the last question is submitted and you push the button "Submit all and finish" Answers are not saved for future attempts once the exam is finished.

If you do not pass any one of the exams with a score of 75% or better within the 3 attempts, you fail the course and do not get the certificate. Sorry but there are no refunds for this. This is an open book exam. All of the answers can be easily found in the book. There are no trick questions.

Time Zone.

Our server operates on Hawaii Standard Time. ( UTC-10 ) So if it's 11pm Eastern Standard Time on your watch, it's still 4 pm the same day on our server. The time and date when you complete the course is the time and date when you submit your first successful attempt according to the server. 
This is the time and date of record that is printed on your certificate. Unfortunately, this can not be changed. If this is important to you, please be mindful of time zone as well as daylight savings time in this regard especially on the last day of the month if your credits are due before the month is over.
