I browsed the materials. With my own experience, the materials here are not helpful at all, but just wasted your time. Believe me, money is not the most important, with offical notes, it will be easier for you to pass CFA. You can save time. Do not waste too much time here.

I think it's a place that can provide second choice to others.
I am happy to have a grouop here, even I got the official notes by $$
