Those are excellent questions to ask when superreading and dipping, especially when you just want to do an extra pass to finish up. It calls on your intuition and inner minds knowledge and understanding about the instructors teaching style to convert the usual who what why when where and how questions into the ones the instructor is likely to ask.
Stick with it too. If you felt you missed the answers as a result of the test... just say to yourself that's the kind of information I was looking for, neutral tone, you're just reminding yourself of a future purpose.
