People fail on one subject, not the total.
The exam requires at least 40% in every subject and 60% overall. Falling short in a single subject fails the whole exam.
The pass simulation scores you per subject against the real criteria and names the subject that is dragging you under. It surfaces the weakness an overall accuracy number hides.
Turn "probably right" into a citation.
Every explanation can be checked against the statute it comes from.
