During the Lent half in D each boy begins to consider the specialist (C and B block) subjects that will prepare him for his university career.
He also chooses a master whom he would like to be his tutor for his specialist years.
Boys almost invariably take up four academic subjects in C leading to either an A-level or Pre-U qualification.
The subjects on offer vary in small measure from year to year, but the following are those currently on offer: English Literature, theatre studies, mathematics, mathematics with further mathematics, biology, chemistry, physics, Latin, Greek, French, German, Italian, Japanese, Spanish, Russian, Portuguese, Chinese (Mandarin), history (one chosen from modern or early modern or mediaeval), history of art, geography, divinity, economics, government and politics, art, design. Arabic courses are available in Options or off-timetable.
Boys sit internal examinations called Trials at the end of the Michaelmas and, where they do not sit external examinations in a subject, the Summer halves.
A small number of boys join the school at the start of C, either as sixth-form scholars or specialist entrants. Details of the admissions process can be obtained from the Admissions Office.
