This passage confuses me. I can't quite tell how the "Your assessment differs" message (lines 172-176) relates to the messages in lines 178-186. 
Is the first one for any difference at all in the entire training exercise (must get at least one of the message on lines 180-182), while one or the other of the other two is for the individual questions that the student needs to match to the instructors' response?

Separately, I think you can consolidate the info in the messages into one line each, even if each one appears on separate lines in the UI. The line feeds separate these related concepts from each other even more, making it even harder to figure out their relationship to each other.
