In the User Interface, when an Instructor clears a grade and adds a new grade in an Original Course Grade Center column, this is considered a normal Attempt Grade and not an Override Grade.  Performing the equivalent actions using REST API causes an Override Grade instead of an Attempt Grade.

2. Access an Original course and quick enroll as an instructor 
3. Enroll a Student
4. Navigate to Control Panel > select Grade Center > select Full Grade Center > click Create Column
5. Enter a desired Column Name with Points Possible as 100 > select Submit
6. Select Create Column to create a second column
7. Enter a desired Column Name for the second column with Points Possible as 100 > select Submit
8. Using REST API complete the following two requests for the first column
