Jay, there isn't much information that you're given that isn't pertinent to the test, but the most straightforward indicator of what will be on the test is the quizzes, since all test questions are either quiz questions or slight variations on them.
The material for these last modules is intrinsically more challenging, which is why you get two weeks to complete them. So my best advice is to use those two weeks very efficiently.
That said, it looks like the average on this test is two points lower than normal, so I will be raising everybody's score on this one by two points.
