Quick question….
CFAI Pg. 525-548
LOS states nothing about calculations, even says candidates are NOT responsible for deriving or memorizing formulas in section 4 to 6.
But then at end of chapter practice problems, all it is is calculations? anyone shed some light on what there looking for here…
The less formulas I need to memorize at this point the better, brain is getting fried.
