DS12 is in Algebra II Honors this year, and I can already see that we're going to have a rough time of it. It's e-school, and the online textbook (Holt, and alarmingly titled as the Common Core Edition) has already shown us two practice problems with the wrong "correct" answers. The teacher emailed him back about one of his formulas in a test problem, *asking* him if it should be something else instead, and no, it shouldn't. And that same test problem was phrased as asking for an explicit formula f(x) when it should have been asking for a-sub-n exponential one instead. This is only week 2.
And I didn't have Algebra II when I was in school, back when the world was young, so we're already out of my useful territory. I have to stay ahead of him in his class in order to have any hope of being able to help him sort these things out.
