We learned to keep an eye on the curriculum four to six grades up after that first year, because she had
inadvertently chosen literature selections which were assigned in later grades.
whoops!
We also realized that in so doing, the school was frowning at us and assuming that WE were the ones doing it on purpose-- for what reason I'm not sure, but anyway. This is why my DD wasn't
allowed to read some novels until they were assigned in High School literature classes, though-- because we had learned that they wouldn't flex around those fixed assignments, so she'd only wind up reading it more than once.
