Hi Percy,
I remember the More/Next thing also. On some of the questions, the question and all of the answers are too long to fit onto the screen, but they don't want you moving onto the next question having never seen all of the correct answers, so you cannot click "Next" until you've clicked "More", which srolls down to show what you havn't seen (I also noticed that More changed to Next automatically once you scrolled down manually and saw all of your answers).
I'm also don't think the
test will let you finish if you didn't give the right number of answers for any question. You can't click too many, and if you click too few, a big red box came up next to the question # on the final review screen.
