When I first started researching giftedness for DS6 I came across Ruf's levels and put him at a solid 3 with a couple of 4 tendencies. I thought that meant he was just "regular old gifted" as opposed to "scary smart gifted". Now that I'm researching the levels a bit more (as opposed to the earlier is he/isn't he question), I'm confused by exactly where level 3 falls on the gifted spectrum. So, what is a "Level 3" exactly and does it give me any real information on him or is just a fun toy to play with?

Also, I've been looking at her book but can't decide whether it's worth $24. So really the same question, is her book useful or just interesting with no real application?

Thanks!!
