The exam consists of a written and operation test. Failing either will require a make-up exam. Make-up fees are subject to local standards. Students can pay the fee and take make-up exams immediately after failing. Make-up exams will be arranged after the normal exams of the day or postponed to be taken along with other students, depending on the local center’s practices. A student cannot fail the exam more than three times. Otherwise, the student will have to sign up for the course and pay tuition again.
