What does it mean to have two chances in Subject 2?

[MacBrielle]

Subject 2's second chance refers to the opportunity to retake the test once after failing the first attempt. Below are the relevant details: 1. Passing criteria: Subject 2 is scored out of 100, with evaluation standards set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; for other vehicle types, a score of 80 or above is needed. 2. Retake: If the first test is failed, a retake is allowed, requiring all test items to be retaken. If the second attempt is passed, it is considered a pass. Not participating in the retake or failing the retake will terminate the current test session, and the applicant must reschedule the test after ten days.
