what percentage of questions would I need to medal at a competitive place like socal? so far I'm averaging about 80%
also how do division c tests compare to division B? are they harder, easier, same?

I'm not from Ohio, but I definitely want to talk about it :)

So how was it? (in comparison to, say, the Westlake test, since that's the hardest one I've taken so far)

Wait, how did you get access to it? You didn't compete it it it seems from your signiture

Oh my gosh I thought it was insane. I don't think I've ever known so little on a dynamic test before. It was in stations, first of all, which I totally was not expecting, and we only had 4 minutes per station to answer like 10-ish short answer + extended response + multiple choice questions. Some stations had giant maps laid out with markers and we had to identify the volcanoes (or other geologic formations) and answer questions about them and there was a lot of gravity/magnetic anomaly math that I had no idea how to do. The test went deeper on anomalies than any test I've ever taken and was definitely harder than Westlake. I think if it wasn't for the time constraints with the station format, I could've done better though. My partner and I hardly used our cheatsheet because there was no time to look things up. I was not expecting to place at all walking out of that test (I felt so bad I almost started crying haha).

I remember seeing a test where they had a picture of the volcano itself and you needed to identify it. But this was in a 2010 Earthquakes and volcanoes test.
What kind of math of anomalies was it?

Sounds fun :) I haven't looked into anomalies much besides the basics of understanding how the different types work, I guess I should probably put some of the formulas on my notesheet.

Oh gosh, I'm not sure I remember entirely. There were some Bouguer anomaly calculations, and a couple related to magnetic field strength/location (??) I think. *sigh* I wish we could get our tests back

For tests should I know about things like streams and deserts?

I wouldn't focus on those categories. Focus more on geologic formations like mountains, trenches, volcanoes, and other formations related to plate boundary.

Well, unfortunately I'm taking on this event with about a month to go before Nats, having not studied a single thing on it due to a teammate being unable to make it...
Anybody have any good advice?

Question: Does the Mohorovičić discontinuity have anything to do with the Gutenberg and Lehmann-Bullen discontinuities?

Moho - the boundary between the crust and the mantle
Gutenberg - the boundary between the core and the mantle
The Lehmann-Bullen discontinuity is a less-used name for the boundary between the inner and outer core. However, there is also an unrelated Lehmann discontinuity located beneath continental crust, the cause of which is disputed (both named for Inge Lehmann, but they have nothing to do with each other).

Thanks! This helps a lot.

Any info on next year's DP topic? Does it stay the same or...

It's been expected to stay the same as of April or so. This may have changed after the committee meetings on Sunday; we'll probably find out sometime in June.
