 Most subjects are examined in all three years; for example, the Natural Sciences Tripos has examinations for Part IA, Part IB, Part II, and in some subjects, Part III.The English and History Triposes have preliminary rather than full examinations at the end of the first year.Degree regulations state that, to be awarded a degree, a student must have passed two honours examinations (i.e., two Tripos examinations) – this could include a Part I and a Part II, two Part I exams, or (in some cases) a Part I and a Part IA.
