The plus side of the oral test is that it is more efficient. Students usually take oral exams quickly, about 10 minutes or half an hour at most. This is much faster than the written test which can take up to 2 hours or the take home test / essay which can take up to 2 weeks to complete. In addition, lecturers are also faster in giving assessments. With the oral test, students and lecturers also have the opportunity to discuss.
