I was putting together a revision pack for our leaving year 11 ICT group the other day. A standard, copy and paste job from OCR. Pretty easy, kept me quiet for all of 10 minutes. Unfortunately while I was putting it together I was tempted to read some of it and came across (somewhat paraphrased I fear as I don't have the text to hand)

"Don't forget sizes: 1000 bytes in a Kilobyte; 1000 Kilobytes in a Megabyte; 1000 Megabytes in a Gigabyte"

Now I'm the first to admit I'm useless at remebering facts like sizes (and generally anything technical about pc's, I just do stuff) but even I know that that is wrong. So I pointed it out to the teacher, that we were teaching these kids something that was wrong. His reply...

"That's the official revision documentation from the exam board, they tell us not to confuse the kids by giving the exact values..."

And we wonder why we're churning out morons...
