has anyone else just sat edexcel S3 on thursday.

I found it ok. One which was annoying me for ages was the difference of 2 means question about pollution. Although it gave the data, and it's a simple formula, I kept getting a ridiculous Z value. In the end (after a mental block and half an hour of sitting blank) I got it to be 6.29...somethin. This still seemed high to be in an exam question.

Did anyone else get this (or the proper answer for that matter) because im still not convinced this is right. Many people I have spoke to got the same, but then again i've heard about 4 different answers going round for this question.

Good luck to every1 in other exams.
