And going into a maths exam with a log book only shows that you can read not that you can do the math..yet that fulfilled the criteria 40 years ago.

My maths teacher taught me how to use logarithms, I was not expected to do the complex mathematical formula needed to tell me whether COSa was greater than 2xSINb, I looked it up in the log book, like I said todays teachers should inform students how to use the internet, it's no different, it's still falls under the remit of 'teaching' and 'learning'.
