It may just be me, but I cannot imagine doing any type of prep for talent search testing. We did try to at least look at the review questions they sent for the Explore so the kids would have some idea as to what the test would look like, but we were trying to get an idea as to what they knew/could do without prep, not what we could teach them to do with a bunch of studying or learning how best to get all the points you could out of the test.

For high schoolers taking the SAT/ACT, etc. I can see doing prep b/c the scores are higher stakes, but at 10 or 11, I wouldn't do it. It would negate the purpose of the testing for me.
