Should we memorize z-score values?

[bluejazzy]

for one tail and 2 tail tests? (90%, 95%, 99%)
ie. 1.65, 1.96, 2.58 for 2 tail
1.28, 1.65, 2,33 for 1 tail?

yes but not required

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

I think there was only 1 or 2 questions relating to Z scores, T stats, P-value, F stat, Chi squared, etc on the entire exam.
I was a bit surprised they made such a deal of it in the books, but tested so little on it.

yes, memorizing the 90%, 95% and 99% is required. It might show up in the exam, also for level 2.
