Wait, PT71?? Right! Yeah, I haven't got around to reviewing it as in-depth as I wanted, so I'd actually like to do that on Wednesday if you're free. 4PM PST / 7PM EST sounds good.
Interesting. You're positive the NA isn't actually necessary? I'm curious about these examples. I didn't look closely at it, but PT71.S1.Q11 seems to be about pollution. Is that the right reference? PT means PrepTest, right?
