extreme data is the data on the either boundary of a range... so if the valid range is 1 to 10, extreme data are 1 and 10, data less than 1 and greater than 10, invalid characters like A,B, or whatever are abnormal or invalid data...
again if a date range is 01/02/2002 to 12/09/2004, the extreme data will be 01/02/2002 and 12/09/2004

as far as I remember, extreme data can only be used with numbers since it requires a range and you can't use range with alphabets, even if you are instructed to enter, say, only from A to D... you either test in such cases using normal or abnormal data

Hello people.

I have a small question related with computing paper 2 question that I have seen a few times.
Basically here the question is 1c. In the mark scheme I understand everything apart from "-10% overheads added". What is this supposed to be?

Also another question is that are you allowed to use a calculator in the exam.

Thanks!
