It really just comes down to personal preference and what works best for you. I personally thought that taking notes was a waste of time and that I was spending far too much time on it. As you're studying and going through each LOS, make sure you understand and can conceptualize what each formula means, not just memorizing them. If an area gives you trouble, work on it until you fully understand it, then mark that area for review later. In college, writing things down helped me remember them and understand them better, but I just found it to be too much with this. The Schweser notes are more than adequate to pass L1 alone. While some people prefer only the CFAI texts, other's find them too verbose and prefer the condensed version of Schweser.
