I think you need to memorize the correspondent values for 1, 2 and 3 standard deviations. Anything related to z-score values will be specified in the problem (with an accompanying table).
no z-table is provided on the exam. dont waste your time memorizing anything related to the z-scores. i did in Dec and never needed it. exam was a joke
