Filling Out Answer Sheets to Insure Quality Grading

 To insure the highest quality scoring with the Paperscorer app:

1. Avoid taking pictures where there is a high amount of glare on the answer sheets caused by light.  This is usually caused by incandescent light directly above a answer sheet.  
2. Avoid heavy erasing or the use of "white-out" type products on bubbles that may obscure the bubble borders.
3. Insure that bubbles are fully filled in.
4. Insure that markings do not cover more than one bubble if this is not the intent.

Using the Paperscorer App to Auto-Grade Bubble Sheets

Once you've downloaded bubble sheets, you're ready to automatically grade using the Paperscorer app.

1. Download and Install the Paperscorer app at the App Store or Google Play.
2. Open the app on your mobile device.  
3. Click the camera icon.  You will be prompted to grant the app permission to use your camera.  Grant permission.
4. Position your device so that the entire answer sheet (including border) is within the frame of the picture.  Hold your device steady.  Paperscorer will automatically capture and display the picture to you.
5. If the picture is clear, click Next.  Paperscorer will automatically score the answer sheet.  
   1. If there are additional answer sheets, continue this process until all answer sheets are captured.​

Bulk Uploading Answer Sheets for Grading in Canvas

Using a standard scanner or document camera, you can choose to scan images of multiple answer sheets and then upload them to Paperscorer in bulk for grading.  To do this in Canvas:

Correcting Errors Found in Answer Sheets

Sometimes, Paperscorer will identify errors or ambiguous markings in an answer sheet.  This can occur if:

• A bubble is marked, but only slightly

When this happens, Paperscorer will present an appropriate message to you and give you the option to review the answer sheet online and manually mark the area(s) that you believe the student intended.  To do this:

1. After uploading answer sheets, if there are errors, click the Correct Errors button.  A page will load in which an image of the captured answer sheet will display on the left and a web form will appear on the right.  The questions with errors will be highlighted on this web form.
2. Fill in the appropriate areas in the form on the right.  
   1. If you do not know what the student intended, you can choose to Skip the answer sheet.  In this case, you can have the student fill out a new answer sheet and upload it again.
3. Continue this process until all error sheets are corrected.
