I would agree that you definitely need to go over the notes, but to me (if I've had more time to prepare for level I) I would have gone through the entire set of video CDs simply because I learn better when someone tells me the info then I read the notes and practise some problems myself. I mean, I find it boring to just read the study notes without using some other tools to help you remember stuff; however, some people would definitely find reading more useful to them (A friend of mine was advising me not to use the video CDs because she found them a waste of time)...
Therefore, it depends. I'd say it's what you think will help you learn the concept better and remember it afterwards which might be different from my way, e.g.
I am waiting for the results to come and I hope to be in a good shape to study for June 2007 CFA level II examination.
