All current MIT subjects are published in the Online Subject Listing and Schedule, which is released about one week in advance of pre-registration for the fall, IAP, and spring terms. (The fall schedule is released during the last week of April; the schedules for IAP and spring are released during the last week of November.) Students may also find these intereactive tools to be helpful in planning their schedules:

Because the online listing is updated throughout the term, it may differ from what appears in the PDF edition of the subject descriptions, which is issued by the Reference Publications Office each August. The Summer Session Catalog contains complete information about summer admission, registration, and subject offerings. In addition, syllabi, lecture notes, assignments, exams, and videos for many MIT subjects are available through MIT's Open CourseWare (OCW) website. Students cannot earn academic credit through OCW, but no registration is required to use the materials available on that site. MIT also offers online classes through edX, a non-profit educational initiative created by Harvard and MIT. However, MIT does not award academic credit for MITx classes, nor does it provide transcripts or proof of registration.

The MIT Class Schedule is a list of all meeting times of classes offered for a specific term. The list is arranged by department and includes subject numbers, sections (lectures, recitations, labs), locations, and meeting times.

Consult the MIT Bulletin (Course Catalog) for detailed information about General Institute Requirements for undergraduate students, general graduate degree requirements, and specific degree programs and requirements. You will find contact information and links to departmental websites in the descriptions of degree programs.

All classes and exams are conducted in accordance with regulations adopted by the Faculty, which are commonly known as term regulations. Undergraduate students will also find this information in the Academic Guide, which has been prepared by the Committee on Academic Performance (CAP) and the Office of Faculty Support (OFS).

Credit for MIT subjects

1 unit ≈ 14 hours of work per term

Represented by a series of three numbers (example: 3-2-7)

  • 1st number: number of units assigned for lectures and recitations
  • 2nd number: number of units assigned to laboratory, design, or field work
  • 3rd number: number of units for outside preparation.

Numbers added together (3+2+7) = total credit for subject (12).

"Units arranged" indicates that the credit is arranged directly with the instructor.
