]I think Mark made a few mistakes, although I'm sure these were typos:
Question 11 MC
He says PDFs aren't image files, yet the answer he gives (D) includes pdf. I think he meant to say C.
Question 16 MC
He says they're links between common primary keys, yet many of the fields he links weren't primary keys. They were unique and *could have* been primary keys, but they didn't feature the key symbol beside them. His answer was A, but I think it should have been B.
Question 3 MC
He says a keyboard swipe doesn't exist, but what's this?
http://www.google.com.au/images?q=keyboard%20swipe&um=1&ie=UTF-8&source=og&sa=N&hl=en&tab=wi&biw=1028&bih=869. It looks like a mobile keyboard an unauthorised user would type his password into. Furthermore, his answer, CCTV, wouldn't have the video quality to see what was occurring on a screen. It might not even be facing the screen and would almost definitely be too far away, and its view may be even covered by the hacker 's body too.
Mark Kelly got Question 11a wrong?
i put =(G6-B6)
because it asks for the weeks growth compared to the week before? he just adds them all...
And what this guy said, too. By Mark Kelly's logic, I could have grown 3km taller by measuring myself every day and then adding those measurements.
That said, I think a lot of what I and chopz pointed out were silly mistakes he made in the rush to publish the solutions online. I'm sure he knows all this stuff.
