Practice helps, lots of practice helps a lot . The test is suppose to challenge even the best students. Most of the time 50% is a good score. My ds has taken the AMC 8 since 4th grade. He is now a freshman. He got steadily better.

Does your daughter have a math counts team. If so this is the type of problems they practice on in Math Counts. Great practice.

Let her know it is about taking the test not the score. You get better but you have to put it in perspective.

It will also be good practice for the AMC 10 and 12 later on.
