Hmmm

I noticed one error. The sum of the primes 1-7 is 1+2+3+5+7=18, but that wasn't an option!

I had to guess for the anagram.

Most of these took only a few seconds and were extremely easy. I'm figuring that the scores are inflated a bit.

Besides which, these sorts of tests really only measure how good you are at taking these sorts of tests.

you are really good at taking these types of tests...
:D

I had noted the same thing with the prime number answer ~ but figured they were trying to word it in a strange fashion.

Their spelling was deplorable ~ so I figured their means of expression was "off" as well...

1 isn't a prime number...

Ahh. See, you can knock a few points offa that inflated score.

You're right, 1 isn't a prime! But I wonder why not?

Wikipedia says: a prime number (or a prime) is a natural number that has exactly two (distinct) natural number divisors, which are 1 and the prime number itself.

Well you could argue that 1 can be divided by 1 and by itself, but these two divisors are not distinct, I suppose. Seems an arbitrary exclusion.

I've always thought it weird that 1 is not a prime number, and I can't seem to find the rationale behind it. It has annoyed me for years.

(And now that I've confessed that prime numbers' issues annoy me, you definitely know I'm weird)

Thanks! I will finally be able to sleep soundly, after all these years tossing and turning in bed, muttering feverishly: "Why not, oh, why not?"

The anagram "California".

I did the test but then at the end found out that they wouldn't show me the result without asking intrusive questions and requiring registration, so I closed the window. Oh well. I guess they figured everyone would be curious enough at that point that they would hand over their email address, age, etc.

hehe - I was going to say 1 isn't a prime number and explain why, but everyone's already said it. :-) Haha - I am such a geek!

I'm not going to do that test, because I am crap at anagrams, so I'd get a very low score, and it would no doubt tell me I am a universal dunce! :-)

[skyring.livejournal.com]

Well, I got the anagram wrong. I guessed there were more cities than states, so I picked city.

I'm no good at the "what's next in this pattern?" question. Add to that, I was taking the test on a laptop, and the tints in the shapes in one section were not very distinct...
