Some of these are a real pain to get.

I came up with most of these after a few days mulling them over. There are a couple though that I would never have gotten even if I had thought about them for a few years.

I got the 19 I wanted to get in the first 10 minutes but then gave up to take repeated attempts at the others.

Some of these are vey dependent on cultural background. I had to finally look up the few that I could not guess.

Yes the first 18 for me came as fast as I could type them in. Then was slowed a bit for the next 5 or so. Finally got 31 of the 33. But the last two I finally googled and when I saw what they were, I would have never got them. My daughter who is a nurse practitioner got the one on chromosomes right away, but the one required you to be from England no one got.
