students at the appropriate level of instruction in mathematics and languages. Hopkins' academics are broken into departments including English, mathematics, science, history, arts, modern language, classics, and computer science. Each of the three class levels — Lower, Middle, and Upper — has a different level of choice in classes. Arts The Arts Department is made up of student organizations and academic classes in studio and performance art. A number of student groups feature performing arts: a cappella groups such as the Harmonaires, Triple Trio, and Spirens; theater groups such as the Hopkins Drama Association; and a variety of choral and instrumental performance groups. The Keator Gallery in Baldwin Hall holds shows of student and teacher art, as well as local artists. Humanities The English Department is the only department in which Hopkins requires a student have at least one class in every semester. Upper-class students have two required semester classes: a college-prep writing course and a Shakespeare-centered course. The History Department core is the Atlantic Communities series that focuses on Europe, the Americas, and West Africa between 1450 and modern times. In addition, elective courses go into detail on subjects such as political science, regional studies, philosophy and religion. Advanced Placement courses are offered in United States History, European History, and Human Geography. The Language Department is divided into two subdepartments: the Classics, which covers Ancient Greek and Latin; and Modern Languages, which teaches four other languages (French, Spanish, Chinese, and Italian are currently offered). Math and Science The Mathematics Department offers study from pre-algebra to Linear Algebra, Multivariable Calculus, Differential Equations and Chaos Theory. The Science Department has three main tracks — Biology, Chemistry, and Physics — along which students can take entry-level courses and then more advanced AP and Honors courses. There are numerous one-off courses in subjects such as Introduction to Psychology, Human Reproduction, or Environmental Studies. The computer science department offers basic computing courses in HTML and Java. Graduation requirements Hopkins' one-room Latin grammar school history is still reflected in its graduation requirements. Every student is required to take an English course every semester, and Junior Schoolers are required to take Latin along with whichever other language they may take, if any. In addition to classical education, Hopkins requires three years of math courses and three years of a language, the completion of Atlantic Communities I, Atlantic Communities II, and either Atlantic Communities III (for a
