How to estimate your score from the IB Security Assistant (SA) 2025 provisional answer key, use the following formula based on the exam’s marking scheme:
Estimated Score=(Number of Correct Answers×1)−(Number of Wrong Answers×0.25)
Steps to Calculate:
- Count the number of correct answers from the provisional answer key you matched.
- Count the number of wrong answers (questions you marked differently than the answer key).
- Use the formula above to calculate the total score.
Example:
- Correct Answers: 75
- Wrong Answers: 15
- Estimated Score = (75×1)−(15×0.25)=75−3.75=71.25(75×1)−(15×0.25)=75−3.75=71.25
This will give an estimate of your raw score based on the provisional answer key.
Note:
- There are 100 questions in total.
- Negative marking is 0.25 for each wrong answer.
