A candidate finishes a part 2 mock with 39 correct answers out of 50. How does that compare with the official pass mark?

1. It is a pass because 39 is above 75%
2. It is a fail because the official pass mark is 40 out of 50
3. It is a pass only if all 7 case studies were attempted
4. It cannot be judged because part 2 has no fixed pass mark
