The Course 2-A concentration consists of 72 units of upper level subjects (with the exception of the REST subject) that have a coherent focus. Students choose these subjects in consultation with the 2-A Coordinator, Professor Lloyd (slloyd@mit.edu) and their 2-A track advisor. A proposed course of study is developed and submitted online for review and approval. Certain restrictions do apply, and are outlined below.

Bear in mind that the 2-A program was designed to be flexible.  Many different concentrations are possible, and a student’s particular program may be unique. The tracks listed below are suggestions. Students are encouraged to design and propose technically oriented concentrations that reflect their own needs and those of society.

Guidelines for Concentrations

**NOTE: The concentration requirements were changed in Fall 2008, and the 2-A program had significant changes in 2012. These changes apply to the graduating class of 2016 and later; the most updated version is posted below.

  1. Concentrations must include at least 72 units.
  2. All concentration subjects must be letter graded.
  3. No concentration subject may also be counted as a GIR (including HASS subjects), except one REST GIR.
  4. One Freshman-level subject, such as 1.00 or 6.00, may be included in the concentration as a REST subject; all other concentration subjects must be upper level.  More info on this post: What counts as upper level?  Note that 18.03 can also fulfill the REST requirement, and also substitutes for 2.087.  Need a REST?  Here’s the list.
  5. UROPs are not allowed in the concentration; however, students may include a 12 unit thesis, 2.ThU.
  6. Basic math and science subjects may not be included in the concentration.
  7. The program of study must include at least 72 units of engineering topics; all content is reviewed by the 2-A Coordinator and Undergraduate Officer.  (Engineering content can, but is not required to, overlap with the Concentration.  Extra engineering subjects can be taken to make up for any engineering content missing from the concentration.)
  8. Each concentration subject must have an obvious relationship to the overall theme of the concentration, and should be explained in the paragraph on the 2-A form.
  9. Students who take Course 2 versions of the 2-A curriculum can use 6 units of the subjects as extra engineering or in the concentration, depending on the subject (see Substitutions).
  10. Graduate courses may be counted in the concentration.
