It depends.
Course Material:
Online: You can view the material right on the website, so regardless of your device, you can view it as it is mobile-friendly. In this case, you would be spending the entire time on your device
Print: You can also download the course as a PDF file within your account by clicking the green tab "Download Course." If you are connected to a printer, you can always print some or all of the PDF file, including the exam questions; this is entirely optional.
All of the test questions are given within the material. This means that you can prepare for the online exam ahead of time.
Online Exam:
For this part of the process, you will need to be in front of your device to
submit your answers.
If you wrote down your answers from the Study Material, then this will be a
fast process as you have already done the work; you just simply need to get
your answers to us via the online exam. All you will do is select the correct
answer for each question, i.e., 1 is A, 2 is B, and so on.
If you have not yet completed the exam from the Study Material, then this will take some time in front of the computer.
After every ten questions, the exam is automatically saved, but you may
always “Save Your Exam” and come back at a later time.
