A quick note... The device requirements should be identified before allowing users to purchase an online version of your course.. Also the course outline that was shown to me had no specifics about the actual material, and or test. I took the test and passed based on the knowledge I already had about aerial lifts etc, but the course outline did not touch on these specifics. There are spelling mistakes inside the exam itself. Your customer service staff was pleasant and helful. Also i would be nice if you automatically emailed a certificate to the holder upon completion of the test... I did it on ipad, and have no way to print the document, other than a screen capture. Please look into the pretest outline content specifically...without general knowledge about lifts, and towing..I would not have passed the course.
