testing plugin for educational site?

Hi, I need testing functionality as follows: students login to read course material ( several large pdf files) and the system stops them after reading ( lets say 5 pdfs) the first day, and doesn’t allow them to proceed until the next day to read the last 5 pdfs. After reading through them the system sends them and the administrator email a login number with a message stating that they have completed the 16 hrs course. Forgot to mention that I would like them to scroll down each pdf and when it gets to the end then the system allows them to click to the next, kinda like terms and agreement do. Is there a plugin to do this?
