I found this comment from the link posted, rather interesting!

"recent information I found from a major New Zealand Dyslexia Awareness association [..]. They found that schools in the U.K. who used Dyslexia Friendly methods in the classrooms had amazing results. By using teaching methods that work well with Dyslexics, the whole class, including the non-Dyslexics, moved forward more quickly than if the class was taught using traditional teaching methods."

Sounds like all kids could do better with Dyslexic friendly methods?

I wasn't dyslexic, but I had a poor memory for facts (still do) and I found it very hard to concentrate on subjects that were not naturally stimulating or creatively engaging, and thus found early schooling quite challenging. As a consequence, I believed I was not very smart.
