I am noticing that all the quizzes have two copies in the folders but they are the same.  Are there supposed to be different versions?

Hi Yoko, the quizzes have the quiz and answer key posted in each doc--that's why they look the same.  Thank you for bringing this to our attention, because we realized that we don't have a second version of these quizzes posted.  We will get them uploaded asap.  Thanks!

Yoko, the requizzes are now posted!

Can you guys fix the black box that appears behind every text box when I download?

Jonathan - we have fixed that issue with the Powerpoint versions. Please make a comment if you come across any other errors. - Melissa
