Roots of Western Civilization to meet the RCB requirement?

Hey, my 4 on the AP Lang Test meets my RCA requirement, but I need to take a class for RCB.

Roots of Western Civilization is interesting to me and will help with breadth requirements, and it also counts to the RCB requirement.

How difficult is this class and is it good for the RCB requirement?

http://www.classics.berkeley.edu/courses/fall-2018/classic-r44 says that Classics R44 can fulfill R&C A or B and one of the 7-course breadth for L&S students (some other divisions may not allow double counting a course for both R&C and breadth, so check if you are not in L&S or want to change into a non-L&S division).

Is there a search to find out what other classes are double count classes? This sounds like an interesting 2 for the price of 1 RCB class.

You can do a search for courses meeting specific L&S breadth categories and see if any courses with an R prefix show up.

Big fail, it turns out that CLASSIC R44 is the only class that can be a R&C combo with a breadth. Says so right on the main L&S Reading & Composition Requirement website. And the class is right at the same time as the CS61A class.
