Not too bad. I'm forbidden from mentioning topics that were on the test though.
If you're not familiar with the test, they have 3 sections each with 7 passages. The passages can be fictional, theoretical, factual, or occasionally real experimental results.
They just so happen to pick a Biology paper that a friend of mine presented a few months ago. It was easily the most difficult one on the test too. I understood it perfectly.
If you don't have anything nice to say, say it on the internet.
