Question to GARP on their facebook page: "Do we get a formula sheet for the exam?"
GARP's Answer: "If a question requires information from a specific distribution table, that information will be provided. With respect to “Quantitative Analysis” topics outlined in the 2011 Study Guide, candidates are not expected to memorize formulas of distributions, but should understand when it is appropriate to use a particular type of distribution. The two approved calculators [sic: more than two calculators are approved] are capable of performing any required present value and future value calculations. Best regards, GARP FRM" -- See here.
