What are the reasons for not being able to schedule the Subject 4 exam?

[DelMicah]

Here are the specific reasons why you may not be able to schedule the Subject 4 exam: 1. Low priority: When there are too many people scheduling at the same time, your priority may be lower than others. There's no need to rush to log in and schedule, as the allocation of slots is based on priority. Even if you schedule early, you may not succeed if your priority is lower than others. For first-time scheduling of the Subject 1 exam, the scheduling time is determined by the date when the user initially applied for a motor vehicle driver's license. For non-first-time scheduling of subject exams, the scheduling time is determined by the date of the last exam taken. 2. System issues: Sometimes, when the system is under excessive load, some students may not be able to schedule their exams and can only wait for the system to be repaired.
