I'm guessing these are the 1級 questions.
I replaced the 2 in /listen2q/ with a 1, and it says "Level 1" at the top, which I assume means 1級. If that's the case, I'm feeling pretty good about being able to pass the 1級. Sometimes I space out and miss details, but I've gotten over 70% right so far (out of 11).
Nice find, Dutch. That's pretty good practice, as it's in the format of the test, and it'll force you to focus on the details (or maybe I should say it forces me to focus on the details). Plus there are some good real-life situations in there, like the train reservations and the best-train-to-take scenario and whatnot. It's been a while since I've heard 指定席 (since I was in Japan). Thanks for posting!
