Many thanks to the ACP PrepCast team! I used their very affordable materials in combination with Andy Crowe's exam prep book and passed first time. Actually the contrast between the two tools is revealing. Andy Crowe covers a lot of what you will need for the exam - and that's all. The Agile PrepCast goes into a lot more detail, and has real education value. Risk Management is a good example: Crowe gives a paragraph on the principle - probably all you'll ever see on the exam. The Agile PrepCast demonstrates risk burndown and other techniques.
