Absolutely. I don't in any way believe that gifted kids should know everything without any instruction. I do also know that a lot of the kids with gifted identifications at dd#2's school got into school programs after doing a lot of outside prep -- Kumon, Sylvan, private tutors, parents purchasing study guides or the actual CogAT online, etc. If the school becomes aware of that, I do imagine that it could be viewed as "cheating" as I said.
I don't think this is what the OP is attempting to do. I am just leary b/c of the fine line that could make the school misinterpret intentions.
eta: maybe taking a look at some of the
online typical courses of study info would be of help? Could you just ask the school for the scope & sequence for next year like I did in math a year or two back?
