DD can do stupid mistakes on tests. Some of it being careless since the question could be simple and she makes assumptions too quickly. She has had to work at slowing her brain down and making sure she is clear on the question. Just training herself. Story: DH and I arrived at inlaws for a visit. I had picked up a bag of food at Zabars. I asked DH to get it out of the guest room. He comes down and says he couldn't find it. I go up and it is sitting on the floor in the middle of the room. DH went to Harvard, undergrad. But this was a typical thing with him. And I see with DD. Sometimes you have to train your brain to work differently. Simple details. A well known CEO said that if you put me in a room with 99 other people and tell a story, I would be the one focused on the flaw in the story. Some people are drawn to details. Others have to train.
