# Concentrations

**Parent**: https://be.mit.edu/
Course 20 is now offering students the opportunity to customize their curriculum with an optional concentration, a selection of courses focusing on an area of interest. Since these classes also count toward the 33-36 unit requirement for the Course 20 Restricted Electives, concentrations allow students to develop their skills and knowledge in a specific area while fulfilling a degree requirement. A [concentration completion form [doc]](https://www.dropbox.com/scl/fi/rwkkqm1enkvwrvyxn58qd/ConcentrationCompletionForm.docx?rlkey=iyf0kjm2e44s0a1ug5dylcewy&dl=0) should be submitted to the BE Academic Office the term in which you plan to graduate.
## Why pursue a concentration
**Acquire depth.** Students in collaboration with their academic advisor select from a list of department-approved courses that provide depth into an area of interest.
**Connect with faculty within a particular field**. Each concentration has a group of BE faculty members committed to providing their expertise in developing the guidelines and selecting the courses for the concentrations. A faculty contact within each concentration is available to provide information and guidance.
**Sharpen your professional focus.** While concentrations will not be designated as such on your MIT Degree, you will be able to showcase a specific area of academic study on your CV and to potential employers.
