When I encounter questions like this, I will send up a quick prayer of thanks that our little princess is not in the GEP programme. This is but just the tip of the iceberg of what they do and I am already drowning in my own confusion! *Head spinning*
I need to meditate on this.
Bye, see you next year!
**Update: Princess solved this question in less than 10 minutes. That was a bit longer than the standard require but given that she has never been trained before in such questions, that is quite an achievement. I, on the other than hand, am still working on the solution. Bordering on hopelessness.
