Hey, need some reassurance or brutal honesty as I just took the SS exam yesterday and may have botched the graphic vignette portion. I did not see any reason in placing the columns in the double height space twice (upper level) and then on the (lower level) precisely because its a double height space. You would build a column on top of a column in the field in a double height space. Does that make sense?
If I did make that mistake then it must be a fatal error.
