Since you are an "almost first time poster" (two whole posts) I will give you an ALMOST FIRST TIME WELCOME TO THE AWS FORUM!!
Interesting question. As a code of ethics is involved in all aspects of the various certifications we get (ASNT, AWS, ICC, City of LA, etc, etc) I should mention one must be very careful how these types of questions are answered. Can't get too specific.
Now, The Code portion of the exam will take you through both RCSC as well as material in Section 16 about bolting which is under several categories. BUT, it also takes you into IBC 2012. I believe you have a choice of 2009 or 2012 when you sign up. Take the 2012, it is the one under consideration, amending, and adopting by most municipalities at the moment. The Building Authorities use a six year advancement but by the time it comes out, gets all the amendments, and changes for city, county, and state regulations worked into it and is accepted for use it is about 3 years behind the published date.
There are several changes in Section 17 on Special Inspections as they apply to bolting. Same with the AISC Construction Manual, make sure you have the newest one as it has changed some in the RCSC.
Multi story. An interesting set of plans to say the least. Mainly watch for things that will bounce you from schedule to schedule so you are constantly going to another sheet several times to answer one question. Notes, schedules, and details. Watch them closely.
No use rating the exam. It does it's job, weeding out uneducated wanna bees. If you have the experience and study beforehand you'll do fine. Some will find it easy, some difficult, some think it is just a money grabber that you automatically pass the second time. Wrong. But then, I and my son passed the first time so who am I to say. We both passed the CWI exam the first time, AWS Bolting Endorsement the first time, and I took the LA City exam and passed the first time. Does that mean they were easy? NO! Does that mean I am better/smarter or just a good test taker? NO! I believe in lots of study and get serious about what you are doing. It isn't a picnic, play with the relatives, go sight seeing opportunity. It is a serious test. Treat it as such and you will do fine.
