I don’t know specifics, you’d have to ask one of the current candidates about that or see if they list the learning outcome statements (LOS) over the years on the CFAi website. Personally, I think you’ll be fine. Use the schweser notes, then review a few of the main topics or ones that have changed or ones you have trouble with using the free CFAi texts. Realistically though, the concepts in the CFAi material are fairly basic and haven’t changed much in 20 years. So yes, they may tweak the direction of the text this way or that way, but for the most part, you’ll definitely be able to pass by studying 2010 material.
