Memorize standard #'s for ethics?

I have heard people saying they saw practice questions asking What Standard # pertains to a partcular topic, like Standard _____ pertains to Duties to Employers. Does anyone know if memorization of the actual #'s is needed?

I don’t think memorization is needed. i’d spend that time memorizing the ratios etc. For standards most questions ask which standard has been violated as opposed asking, is it V(B), I© etc etc.
