Definitely read Schweser and do CFAI eoc. They are not around this long and trustable if they suck. Unlike level 1 the material that can be tested are not that varied imo. But wow I hate pension but at least there is only one template. Intercorporate investment is gonna be the worst.
CFAI books are necessary. Schweser/Stalla as good as they are cannot copy wording for copyright reasons and miss exact wording that ends up on the exam. Ideally, study summaries then read CFAI Text. Though a little too late for that…
