I hope they finally got the Navy-Marine Corps Uniform topic right. In all of my four years, I don't think the errors were ever corrected! In reality, pro-quizzes should be taken seriously -- not because it is "another" task for plebes, but it is something (knowledge wise) that you can actually use after you graduate.
If you are a plebe, when the warfare/platform topics start appearing, this is a good time to ask your upperclassmen (and prior enlisted) about how it applies in the Fleet/FMF -- remember some have been on summer cruises/evolutions and seen some of this cool stuff in action.
