We also let ChatGPT provide answers to parts 3 & 4 of the Pre-Exam.
Some practical difficulties were that only plain text could be entered, which means that in part 3, the figures couldn't be provided, and that the underlining when indicating amendments was not present.
If one would consider our answers (see seperate posts, which are not necessarily correct!!) as the intended solution and applied the Pre-Exam's marking scheme (all correct: 5 points, 1 wrong: 3 points, etc), ChatGTP achieved 16/50 points which is well below the required passing grade of 35 (normalized from 70 for the entire exam to 35 for parts 3 & 4) and rather a score associated with mere guessing.
