Create Online Course Using Wordpress Or Moodle

I am trying to create an online course for my site, I would like this done in word press if possible and need it to do the following: 1. I need each student to be able to save there current progess and return later if desired. 2. I need each course to have a timer so that they are not allowed to finish the course to quickly. example course 1 should be completed in no less then 20 minutes so if they complete it in 14 they can't continue to the next course. 3. as I stated before there will be multiple courses so I need some way of track that each user has already complete course 1 , 2 , and 3 but has not yet complete 4 or 5
