I'm sure a great number of people are curious, I for one, am. Would you mind posting the changes here to help everyone out?
Of course, I don't mind one bit.
So the biggest curriculum change is that NAV/NOS has been combined into one class called Watch-Officer. You take two quizzes and a test on Watch-O (a quiz on Watch-O knowledge plus Charting and Maneuvering Boards, a quiz on Rules of the Road, and the test on both) with the quizzes being worth 20% and 10% respectively and the test worth 70%. This one class is easily the biggest educational challenge you'll face. You'll take the Watch-O Quiz in Week 7, the RoR quiz on the Monday of Week 8, and the Watch-O test on the Friday of Week 8. It's basically your last hurdle before Battlestations (Capstone, which has changed drastically).
The rumors about History were correct, you still take the class but there's no quizzes or tests. Later you will give presentations during CandiO Phase on an approved history topic of your choice that will be sat-in on by the history officer and any staff who have an interest in the topic. It's an easy 15 minutes long and done with a group of your pals no larger than 4. Have a bit of fun with it.
Naval Orientation Warfare has been changed to Division Officer Fundamentals. DivO Fun. takes place during Indoc Phase and if you're a prior the toughest part will be staying awake. There is a quiz worth 10% and a test worth 90% of the class, study for them and approach it like you would the other classes at OCS because it's just like how the other classes besides Watch-O are set up. The knowledge is a mile wide and an inch deep; the questions on exams come from the enabling objectives. DivO Fun. covers everything from customs and courtesies, to what education opportunities exist for sailors, the basics of ship life such as what the Wardroom is, and knowledge about things like Navy/Marine/Army/Air Force command structure and Fleet locations. As a non-prior I enjoyed learning about things like customs and courtesies but YMMV.
The last change to curriculum is that you will do a Leadership and Ethics Presentation during CandiO Phase. These groups and presentations are assigned, and they are about 50 minutes long. They are sat-in on by your Class Officers and sometimes your RDCs as well as any staff who are interested in the topic.
Besides those changes his videos are spot on.
