How many times can Subject 2 be scheduled?

[Isaac]

Subject 2 can be scheduled up to five times. Here is extended information about the examination rules and precautions for Subject 2: 1. Examination Rules: (1) There are two opportunities during the examination, requiring all five items to be passed in each opportunity. If any item fails, all five items must be retaken. (2) If the first examination fails, the second examination follows immediately, with the same process as the first, using the same vehicle and the same test track, and fingerprint verification must be performed again. 2. Precautions: (1) Managing emotions is crucial. Many students who fail Subject 2 do so because they cannot alleviate their nervousness after hearing the failure announcement, leading to repeated mistakes at the same spot. (2) The second retake is the same as the first examination; during the vehicle preparation, it is essential to adjust the seat, mirrors, and fasten the seatbelt before fingerprint verification. (3) Each examination item in the test center is monitored by GPS positioning. The control line (yellow dotted line) of each item represents the examination area for that item. Once the vehicle's front passes the control line, it signifies entry into the examination for that item, and the examination rules for that item must be followed to completion.
