My DD10 skipped 5th Grade. She has still had straight As all this year, but it has actually taken her more effort. It was a good move for this year but is only a temporary fix. The curriculum at her school is very repetitive from year to year and she just really doesn't need that so, she is getting really bored in Math and History. Also, the Science covers too many subjects in very little depth each year which is also frustrating. Next year we are going to homeschool her so she doesn't have to do so much repitition and can engage in more depth.
