Raising an objection
Challenges must be submitted within the objection window and supported by a credible reference. Where a challenge is upheld the correction applies to every candidate, not only the person who raised it.
Calculating your score
- +1 for each correct answer
- −1/3 for each wrong answer
- 0 for unattempted questions
A candidate with 70 correct and 20 wrong scores 70 − 6.67 = 63.33 marks. Because shortlisting uses normalised marks, treat this as an indicator rather than a final figure.
