Hi All, I just took the PDR and with big surprise I scored only 50%. Thing is, some of the answers the system is suggesting are clearly wrong (kurtosis in a normal distribution not zero?) I am wondering if buying those preparation material makes sense or it is just a waste of time and money.
Kurtosis in a normal dist. is 3. EXCESS kurtosis is 0 Kaplan has worked wonders for me…
schweser you mean? anyway you are right on kurtosis
