I wasn't sure whether or not to use the "force User to enter answers in order" function. On one hand, someone could complete this quiz by typing in all the S.I. units; on the other hand, based on the published S.I. units quiz, it seems as though not all the S.I. units are well known.
If you think I should implement the answer-in-order feature, please say so (It would probably give me an excuse to edit style, too...). In the mean time, enjoy! |
