SDN Members don't see this ad. (About Ads) I know MKSAP 5 just came out, but was hoping people could shed some light: Do MKSAP 4 and 5 overlap, i.e. have similar/identical questions? Or is it like MKSAP 3 vs 4, where everything is organized differently with differing questions? In other words, should I plan on doing MKSAP 3 & 5 only, or is MKSAP 4 still also useful?
