We're the other way around. My DSS, who struggles academically in high school, has been doing great over the summer. DS6, who had a relatively good year in K despite being 'bored'(even with being given 2nd grade levl work to do), appears to be missing the structure that school provdes and has told us a number of times that he's "a little bit sad" about not being in school. Nopt what I would have expected at all.
