Whats the difference between the online and cd-rom versions of this course?
The cd-rom version of this course includes a timer that will require you to spend at least 45 hours on the course. It can only be installed on a single computer. If you would like to be able to work at a quicker pace or from multiple locations, you should purchase the online version which will only time the exams and allows you to work from any internet-connected computer.
