I prepared for the US RAC in 2014. I created a syllabus and ran a little study group. Different areas were represented in the study group so we could all contribute real-world stories from our experience. Here is the document. It took me about six months to go through everything. It's a little dated, some of the links might be broken and there are a couple of rough edges, but it might help.
Also take a look at the FDA website, they have a LOT of teaching materials.
Good luck!
