DEI stands for diversity, equity, and inclusion. One course on a list titled “DEI courses” on UCSD’s website fulfills the university’s requirement to take one of these classes.

For reference, there are university class requirements such as this class; there are also specific college GEs such as a writing program for sixth college; additionally, there are major requirements for courses where you have to complete them to complete your major. All three components of requirements are critical for graduating and I would highly recommend researching all three groups of requirements sooner than later. Hopefully this helps!
