Yup. I'm working with those as well as the new OAT book. The challenge is working out what you actually need to know. Each book has a different perspective and whilst each remains valid, the content varies quite a bit. The books even say that their content exceeds the JAR syllabus which isn't particularly helpful when I've been told that much of what you have to learn isn't really needed. Never mind, I'll just keep plugging on..........
