Hi All - first of all thank you for using the Forum and thank you Keith for helping us out here.
About answer keys: in order to keep user data stable and avoid corrupting results and answer keys, especially as we move forward with our PowerSchool and Skyward integrations, we made a change last month to the way you would change an answer key. We did this because our database was constantly recalculating scores and the whole thing was too fluid, and too easy for people to make mistakes, and it was too hard on the database to have people adding and removing questions, changing the key, etc...
So, as of last month, once your quiz has results, you can no longer change the answer key. This means that once you start scanning, that quiz and those results are "locked" and this makes it much easier for us to make sure your data have 100% integrity.
But you can still change the key! You just have to do it in a more formalized way. Here's how:
Step 1: if you have a quiz that already has scanned results, and you want to change it somehow, go onto the web app and make a copy of the Quiz. This copy function is available next to the "Edit" and "Delete" buttons in the Quizzes page of the Web app (we will be adding this button to the mobile app too, soon. But for now if you are mobile only you can still log into the Web app from your device and do this if you don't have access to a computer).
Step 2: When you press "Copy" you will see the new copy of the Quiz in your quizzes list. Go ahead and edit this copy however you want, and change the name, too, so you know which version of the quiz is the "new" one.
Step 3: Rescan your sheets for the new quiz, and you are done! Now all of your results will reflect the changes you made to the quiz.
I know that this is not as convenient as being able to change the quiz at any time, in any way you want, even after you have already scanned the results, but this new way is much, much better from a data reliability standpoint, and I know integrity of the data is of the utmost value. This new method will also allow us to keep the data 100% correct when we implement the PowerSchool integration later in March 2015.
Last thing: I would recommend you delete the old quiz, with the old answer key. It is no longer relevant and can only add to the chance you'll accidentally view those results instead of your "real" results (the ones from your new edited copy of the quiz). ALSO: PLEASE DO NOT TRY TO GET AROUND THIS BY DELETING ALL OF YOUR RESULTS AND THEN EDITING THE QUIZ. This will "work" right now, but soon this loophole in the system will be closed. But even though it works, it is a terrible idea to make our database turn somersaults like that. Your quiz results are almost sure to be corrupted if you try to use this workaround. Please simply make a copy of the quiz you want to change, then make your changes to that copy, and then scan the sheets into the new quiz. This is the cleanest way and it assures 100% data integrity.
And if you have comments about how to make this process better, I would love to hear them. But please understand we did this to make sure your data are protected from corruption, which we can all agree is very important.
I'll check back here for your reactions to this, and also please let me know if this solves your problem.
