I'm unable to access previous lessons to prepare for a review lesson. This puts me at a disadvantage

Hello,

You can view past lessons by clicking on "View Past Lessons" underneath the class heading. With that said, you have to complete a lesson for it to populate in the pervious lessons. So if you did not start from Lesson 1 or skipped around, you may have areas that you did not cover and they will not be in your Past Lesson history. 

In this particular case, which lessons are you not able to access?
