In all of the term structure models, we have "dw" serving as a normal random variable, in which David recommends to use Norm.S.InV on that uniform random variable. I'm curious if anyone could provide how to prepare for this, given that there is a "randomization" factor in the model that's been shown on BT to be a formula in excel. How would we be expected to execute one of these models on the P2 exam?

Thanks
