I just guessed on some of the questions so 125+ IQ points doesn't seem reasonable...

I got 100% and 125+ isn’t very specific.

Poorly worded, illogical questions and not even an IQ test. Prior knowledge should play no part and I would say that counts double for biblical knowledge!

Q1Kate, who is 16, is four times as old as her brother. How old will Kate be when she is half as old as her brother?

Dont you mean how old does she have to be for her brother to be half as old as her?

Well done.

I don't agree with others. The quiz wasn't the worst one. I got 125+

Agree to this being a horrible test. Depending on how you think critically/ analytically, some questions will have people come to a different answer than the one that is listed as correct. Not to mention, for some of these you have to have knowledge about the subject at hand. Not everyone will be familiar with creation myths, such as the biblical flood. A question relating to religion has no place being in an IQ test.

I'll give a different example than Mark. For #7, one could think that four would be the number that does not fit if you are looking at the numbers in ascending order. Five is the only odd number, sure, but the most logical conclusion would be ascending order because the rest of the numbers follow that pattern, except four.

To the creator of this quiz, good try, but it was a poor attempt.

I have to agree with the first guy. For instance the first question is all messed up grammatically/logically. At first Kate is 4 times older than her brother, and then we are asked at what age she will be when she is half as old as her brother...not possible.

I could go on...but why bother
