 The student was then considered an " inner barrister " , and would study in private , take part in the moots and listen to the readings and other lectures . After serving from six to nine years as an " inner barrister , " the student was called to the Bar , assuming he had fulfilled the requirements of having argued twice at moots in one of the Inns of Chancery , twice in the Hall of his Inn of Court and twice in the Inn Library .

After five years as an " utter " barrister he was allowed to practice in court — after 10 years he was made an Ancient .
