There are several kinds of exams that can be taken. An ORAL exam is a type of exam where the student is asked questions orally by an examiner. A viva is similar to an ORAL exam, but it is usually more in-depth and involves more discussion. A FINAL exam is typically taken at the end of a course or program and is used to assess the student's overall knowledge. A BAR exam is a type of exam taken by those who wish to become lawyers. An ENTRANCE exam is a type of exam taken by students who wish to gain admission to a school or university. A midterm exam is an exam taken during the middle of a course or program. An openbook exam is a type of exam where the student is allowed to use reference materials while taking the exam.
