The mocks live here, and so does what they told you. Nothing here is a grade: every part can be done again — with the support, and then without it.
The Cambridge Scale for C2 Proficiency. The mark appears once you have sat something — it is an estimate from your unaided attempts, not a prediction.
The three mocks are a ladder: with the support open, then with it when you need it, then under exam conditions.
Every part opens with its support showing. Work with it, check, then clear it and try the part alone.
Attempt first. If a part goes badly the support appears, and you do it again.
Nothing is checked until you hand in. Then every part at once, and the support for the debrief.
These are the parts where you opened the support. They are not failures; they are the parts to come back to. Two returns to a part beat one more whole mock.
