The first couple of chapters of this were interesting, but then it drifted into later centuries and became less relevant to me. (Tbh by the time you get to 1480 I hardly think of it as medieval at all, and that's several centuries after it stopped being pertinent to my exam.) Plus, because I know less about this period, it was difficult to know if these chapters were telling me anything new. The earlier ones helped confirm and remind me of some key ideas, at least.
