Apologies for not getting to this while voting was ongoing, but the intent of the "Engineering Undergraduate" option was to be a First Year 'General Engineering' student, i.e.: in an interdisciplinary program that sometimes universities offer to let STEM majors knock out prerequisites and get exposed to a variety of fields before switching into something more appropriate to a career.
As stated explicitly in the explainer tab, the main advantage of this is being better at boozing it up and retaining slightly more complete STEM knowledge than the others.
In all cases, Charlotte still has the benefits of a 21st century education up to a high school diploma and access to common resources.
