The passing score
NCC exams are criterion-referenced: there is no set percentage. Pass/fail compares your ability level with a predetermined standard.
Because there is no single published number, aim to be solidly strong in every content area rather than chasing a percentage you read online.
If you need to retake it
You can retake the exam if you do not pass: wait 45 days after the test date to reapply and pay all fees again. NCC sets no limit on the number of attempts.
How to use this to plan your preparation
- Check your starting point by area. Take a mixed set of questions and look at your results per content area, not just the total. The real exam has 175 questions (150 scored, 25 unscored), so practise in blocks that match its pace.
- Work the weakest area first, in short sessions, and read every explanation, including the questions you got right.
- Finish with full timed practice that matches the official time (3 hours), so the length of the exam is not a surprise on test day.
