Better Call Saul. I find it so amazing how they were able to take an existing (brilliant in its own right) story, and extend it in both past and the future. It fits in so nicely. There are very few (if any) plot holes, and the story is enjoyable in its own right. Add to that the superb acting of almost everyone, and the elite cinematography. I don’t think there’s a single aspect of this show that I don’t like.
Were all the tests available at the same time? Usually there are different times for submitting tests and also for assignments. I’ve never taken a course where you can just submit them whenever you want. For assignments, maybe, possibly with some penalty. But never for tests.
