Study guide Ch. 4 "Image Transfer" & Ch. 5 "Image Sensors" test
In both chapters, but especially 5, the text gets pretty technical in terms of how images sensors and JPEG compression works, so I'd suggest beginning to study for your test earlier than a lot of you did for the last one. The format for the test will be the same; you'll need to choose the best answer for roughly 50 multiple-choice questions with a few bonus questions thrown in at the end.
