Yeah, this was a pain for me. It's a long and fairly difficult exam, and you are not likely to remember what you answered if you return to the d/d questions after getting to the end of the exam.
Make sure you have a strategy for these going in. Another way to do it is to write down your answer on the markerboard that the
test center provides (or enough of the answer so that you remember what you did). Whatever strategy you use is fine, as long as you have one.
