How long is one study hour for Subject 3?

[MacEmmett]

Each study hour for Subject 3 is 60 minutes, with effective teaching time required to be no less than 45 minutes when clocking in study hours. According to regulations, examinees can clock in a maximum of 4 hours per day, and any study hours exceeding 4 will not be counted. The "Motor Vehicle Driver Training Teaching Outline" stipulates that for common C1 and C2 driver's license tests, 24 study hours must be completed to schedule Subject 3. This includes 2 theoretical study hours and 22 practical in-car study hours. For A1 and B1 licenses, 20 study hours are required, while A2, A3, and B2 licenses require 22, 33, and 32 study hours for Subject 3, respectively. For clocking in study hours, trainees generally need to input their fingerprints during practice, and then the instructor must swipe their card to prevent cheating by substitution. Some regions have also begun implementing facial recognition for clocking in, which is a more convenient method.
