EandCmom,
Good luck to your DS on the Explore Test this weekend! My son was able to make his afternoon game the day he took the Explore, but this Sat, he has the district band solo competition so may miss the last regular BB game with his community team. They are also currently (tied, maybe) in first place.
I bought two prep books for the ACT my kids are scheduled to take in April. Aside from the fact that they are really busy with other interests and requirements, they have no desire to look at the books, much less any intention of taking practice tests!
They parrot back that the sitting in April IS the practice test!
