The whiteboard raises something, I'm sure of that, but can't remember what. It might possibly raise more than one skill. There's options for using it, like writing equations (logic?) or creating sports plays (athletic? charisma?).
I think the business planner might raise charisma, but it's been a while since I played a business student who actually studied with it.
I don't think the brain enhancer raises logic or science. It does have a huge list of skills. Chuckles, if you send a sim to check the options available, make sure they don't have any maxed skills. The machine won't show the option to raise skills that are already maxed out.
