So the grading issue was corrected from yesterday. Today when I clicked on Unit 8, there was only one lesson showing when there should be two. I still reviewed it. When I went to re-attempt the quiz, there were NO SUBMIT buttons that should be there after each question. I was using my iPad so I used my desktop at work and even worse, I could not even access Unit 8 AT ALL!!!!!!! So now I have to wait until that's fixed. Wow!!!   UPDATE: Even though there was no SUBMIT button, I still answered the questions, hit the NEXT button and then the FINISH REVIEW button. The answers went through. I just didn't get to check each one before submitting which is even better :-).
