While I wasn't present at the official test I did hear parts of the wppsi 4 they did for the morning study. Most of it wouldn't have helped but I think I could have coached the vocab section pretty well. I don't think that would help a lot tbh though unless the child did equally/almost as well in the other sections. It would look suspicious if they were on the 99th percentile for one test and around the 70th for everything else.
