I recall one question she told us about where they asked about something that was hot and dry during the day, but could get cold at night. We asked her what she answered and she told us she couldn't remember what she told the testers, but that the correct answer was a desert. She thought it was funny and laughed about it - much to our chagrin. We don't know if they caught her in the act or not and took that into consideration. The report we got didn't say anything about it.
My mother took my brother and me in for testing on the same day. My test took quite a bit longer than predicted, so my brother had to sit in the waiting room for a long time waiting for me before his test started. He got out much faster. On the way home, he told my mother, "Mommy, I tricked that lady!" She asked how, and he said, "If I gave her an answer that was wrong, she stopped and asked me questions about something else!"

He still squeaked into the gifted program, which was the only reason we were tested, so she didn't follow up on it.
