The point they are trying to make is the current training provided at the location you state is not as effective without the supplemental PDF files. For example, the training mixes video (useless in my opinion) text screens and forms with popups that are only available while you are viewing the website. I am unable to retain information using this teaching method and need a review document such as a technical guide or course material in the form of PDF. I am unlikely to be able to pass the exam without something other than your web study aids. I do not plan to spend hours taking screen shots or transferring the information to paper. I have also taken the web online classes which have PDF file which in some cases are just a bunch of screen shots which are not always helpful.
