LOS vs Study Book - Kaplan Schweser

Hi all, it is the first year that I focus on the LOS (I have ordered the flashcards from Schweser) and I am a bit confused. For SS1 and 2, there were no big differences. However, for SS3, a few topics were not covered in the LOS flashcards. E.g. BB&K model, Pompian, Barnewall model, prospect theory, etc. Thus, do you think it is better to focus on the Schweser Notes and learn all these concepts or is it a waste of time and I should be fine with the flashcards? Thanks in advance for your help.

You want to learn from flash cards?

Partially, yes. As they treat all LOS, I would expect that they cover everything I need, except the exercise…
