There's a website called Albert IO that the school gave the students subscriptions. They had to run through various amounts of it for homework as test prep. The kids said it was stuff teachers submitted so wasn't professional test questions.
As far as the format for writing essays, my kids took a history test before taking any AP courses and did quite well. However, in later AP courses, the teacher had a different way to write that she said was what AP was looking for. Mine stuck with their way (and got lower class grades for it) but got 5s on the tests. I think finding a second opinion is always a good idea.
