If you already have a memo or a marking guide, you do not need to retype it. Paste it into the mark scheme and let it do the work.
Using your memo
Open the lesson from My Library and click into the question you want to work on.
Paste the relevant part of your memo into the Mark Scheme field, then tidy it so each mark is clearly attached to something.
Making a memo work as a mark scheme
Keep the mark allocations. "[2]" against a point tells the marker what it is worth.
Split a long paragraph into one line per credited idea.
Drop the front matter. Instructions to human markers about admin do not help.
Set the question's marks to match the memo's total.
A whole paper at once
If you are working from a full past paper rather than one question, the Educator Agent can build the lesson and the mark schemes together. Put the questions and the memo in the same file, or it will write a mark scheme that may not match your paper. See Turning an existing assessment or past paper into a lesson.
