How long until the bugs are worked out?

I'm a few short days from taking the exam. I use the practice exams to stay fresh. 100% forward and backwards. I take the exams every morning, and now am reviewing some of Prof. Messer's videos. When I select to take the practice exam again all that shows up are the results from the previous attempt. the OSI and ports test haven't been migrated yet.
Not a good time to lose that edge.
