Extra instruction
From USAFA Folklore
(Redirected from EI)
Extra Instruction (EI) is one of the benefits of being a student at the Air Force Academy. Faculty members are generally ready and willing to provide EI to cadets who need help or want to learn more about a subject matter. Instructors commonly give their home phone numbers to students and publish their office hours.
EI has also been called the "Extra Inch", in derogatory reference to how some cadets use it as a method of sucking up to their instructors for a higher grade, as in "Don't forget your kneepads for your EI session".
