请看cfa book1 p95-96的一段问,摘录如下供参考:
It is very important that you be able to use a financial calculator when working TVM problems because the exam is constructed under the assumption that candidates have the ability to do so. There is simply no other way that you will have time to solve TVM problems. CFA Institute allows only two types of calculators to be used for the exam--the TI BAII Plus(including the BAII Plus Professional) and the HP 12C(including the HP 12C Platinum). This topic review is written primarily with the TI BAII Plus in mind. If you don't already own a calculator, go out and buy a TI BAII Plus! However, if you already own the HP12C and are comfortable with it, by all means continue to use it.
