Sometimes it makes sense, to drop out of honors, but not always.
My daughter tested into compacted math at the end of 5h grade. Her 6th grade math teacher was good and she did fine. Then, she had a terrible math teacher in 7th grade. It was suggested that she, along with quite a few more students, might want to consider dropping to the grade level class in 8th grade. I knew my daughter was a capable student provided she had a competent teacher. I rejected the suggestion, explaining that she would have private tutoring over the summer to shore up her skills. She went on to do Integrated Math 1 in 8th grade and she is absolutely acing it, one of the top students in her entire grade. Having said that, the plan was to give my daughter solid math skills and to give her added flexibility so that she may fit in marching band in high school and still be able to graduate with either AP Calc AB or AP statistics.
Sometimes the purpose of hiring tutors is not so much to bump up the grades but to make sure that the kid gains the skills that the kid, for whatever reason, is not learning in class, especially skills that are foundational and non negotiable.
