Quanave Fnance and Invesmens Advanced Formula Shee Fall 2017/Sprng 2018 Mornng and afernoon exam bookles wll nclude a formula package dencal o he one aached o hs sudy noe. The exam commee beleves ha by provdng many key formulas, canddaes wll be able o focus more of her exam preparaon me on he applcaon of he formulas and conceps o demonsrae her undersandng of he syllabus maeral and less me on he memorzaon of he formulas. The formula shee was developed sequenally by revewng he syllabus maeral for each major syllabus opc. Canddaes should be able o follow he flow of he formula package easly. We recommend ha canddaes use he formula package concurrenly wh he syllabus maeral. No every formula n he syllabus s n he formula package. Canddaes are responsble for all formulas on he syllabus, ncludng hose no on he formula shee. Canddaes should carefully observe he somemes suble dfferences n formulas and her applcaon o slghly dfferen suaons. Canddaes wll be expeced o recognze he correc formula o apply n a specfc suaon of an exam queson. Canddaes wll noe ha he formula package does no generally provde names or defnons of he formula or symbols used n he formula. Wh he wde varey of references and auhors of he syllabus, canddaes should recognze ha he leer convenons and use of symbols may vary from one par of he syllabus o anoher and hus from one formula o anoher. We rus ha you wll fnd he ncluson of he formula package o be a valuable sudy ade ha wll allow for more of your preparaon me o be spen on maserng he learnng objecves and learnng oucomes. 1
