Paste the methods below in Chrome Console (Ctrl + Shift + I), and then convert the data into JSON string using:

JSON.stringify(data);

Paste that string as a parameter to `prefillSubjectsAndGrades` method.
Example is given at the end of this file.

NOTE: If the fields change (their `id` values in particular), then the algorithm will break, and is rendered useless.
