Reset battlefield version of chapter 3 mini-quiz

I modified the battlefield version of the chapter 3 mini-quiz, so that it has more graphics files embedded. These will make it an even better test tool. The new version is capitalized:
BATTLEFIELD version, ch. 3 mini-quiz.

To do the new graphics, I had to re-set all attempts. A bunch of you have already tried the battlefield version, but re-setting means I had to ditch your attempts. So: If you have already tried it, do it a few more times, just to be extra sure.

REMEMBER: make sure to take the "battlefield" version of the chapter 3 mini-quiz, before you take exam 1, to make double sure that your browser and internet service can handle the exam process. If your computer flakes out on you in the middle of the exam, there is noting I can do, and you'll be stuck with whatever points you have scored before the failure.

If your web browser or internet sevice cannot handle this one, you had better make it your business to find a place to take the test.
