Hello Shannon,
I'm not sure I understand what you mean by "study modules". Would you please define/describe what you are looking for?
Essentially, the PrepCast is a study course that consists of about 160 or so video lessons. For easier access, we have grouped them into modules as part of the LMS. Have you already watched the "How to login and navigate around" tutorial that you can find on the login page? Here is the direct link to the video:

Never the less, please let me know what you mean by the study modules. We are currently in the process of improving customer-facing information. So this might be something we have to work on.
