My DS12 took it yesterday also. It was his second time. The first was the only prep, despite the fact that I had bought the online Kaplan prep through homeschool coop. He has never even logged on, partly due to a long commute to and from school and a heavy workload, but mostly due to refusal to practice for a practice test.
He was unhappy that the tester made everyone in the lecture hall do the essay first thing even though I had told him that he wouldn�t have to because he was registered through a talent search. I wanted him to reserve his energy for the math portion.
He didn�t quite finish most sections, but felt confident that his completed math selections were correct. We will see.
