I also have driving licence(from home country) and go for short course but after having pre-test (which is not mandatory)they forced for full course and according to other student it is their practice especially for short course student and important is they never tells students about such so called pre-test at the time of admission after having few classes they inform you about pre-test which is unfair........ while with karawa after completed the classes you can go directly for test with police department(which is quite normal).
