Dearborn has updated test materials for the Series 24 examination in anticipation of coming changes to the National Association of Securities Dealers examination. The company's new PASSTRAK Premier Set, which includes an interactive Series 24 license exam manual, state-of-the-art drill and practice examination prep CD-Rom, and a print practice final exam set, will be available to buy and be taught in classes across the nation. The new examination reflects changes in over-the-counter trading and market-making regulation and includes 25 additional questions, primarily covering this information, sales supervision, and customer accounts.
