Understand the marking
Score = correct answers − 0.5 × wrong answers. The percentage uses all statements, including blanks. The official threshold is 50% for standard Basic and 60% for Condensed Practical Basic. This does not predict the practical result or certification.
Example: 70 correct, 20 wrong, 10 blank → 60 points / 100.
Example: 60 correct, 40 wrong → 40 points / 100.
Example: 60 correct, 0 wrong, 40 blank → 60 points / 100.
