You can go to the driving school where you enrolled at that time, or log in to 12 123 to find out whether you enrolled in C 1 or C2. C 1 is a manual driver's license and C2 is an automatic driver's license. Compared with C 1, C2 is much easier to learn, because an automatic car has no clutch, so it doesn't need to step on the clutch frequently to shift gears, just use the brake and throttle to control the speed. The driver's license of C 1 can drive C2 and other manual cars, while C2's driver's license can only drive automatic cars, not manual cars.
