I have a 12 year old (7th grader) who I was thinking of having take the AMC 8 exam. The issue is that she has not done very well on the pre-test (scores of 6 and 8).... so now I am thinking of maybe not having her take it. I was wondering if anyone has any experience with this exam? Are there things that you can do to increase score (practice) that would help in only 2 weeks, or do scores tend to be very stable. Any insight would be appreciated!!

On a separate note, I am concerned as to why her scores are so low.... would this point to maybe problems with what she is being (or not being) taught at school?
