[Year 12 IT Apps] IT applications 2007 exam: assessor's report

Tue Apr 22 21:24:58 EST 2008

At the risk of seeming a bit wide of the Mark ;-) This situation is what 
double entry validation was invented for, if there is no other obvious 
method (eg for password entry) enter the data twice and compare - it is 
reasonably unlikely that the same typo would be made twice.
