This exercise is the same as the last one, except that
if you score your A4, and you fail, you will get a new A4.

This is just in case you got into the habit of scoring, looking at your A4,
and then hitting the raise or lower button a few times until you pass.

(You wouldn't do that, would you?
Well I did, so I thought I'd put the kibosh on that, just in case.)
