I sat it with the online classroom and I don't think you actually learn anything new, but they break down exactly what the markers are looking for with a checklist of things to include for each part of the exam. I would say its invaluable just for that checklist, with which you can pick up a lot of easy marks just by running through in the exam. For me though i could have printed the checklist from each section and not watched any of the videos and it wouldn't have changed much, so its a shame thats not available on its own!
