hi again gratified:

DD8 is in a similar boat. Her reading comprehension scores don't jive. This can be indicative of a LD, such as a processing issue. Spelling that doesn't seem to match up with what you would suspect would strengthen that assumption.
In DD's case, though, she whips through the test because they are easy. So easy she actually loses interest while she is taking them!
I've attempted to teach her test taking strategies.
Also, sometimes the answers to multiple choice tests seem illogical to a highly intelligent child. Have you ever seen those questions? Who writes that stuff?
