We went back and looked. DP Jr. submitted a scholarship application, so it now says “Thank you for submitting your scholarship application to The University of Alabama for the 2018 - 2019 academic year. Should you be awarded any scholarships you will be notified by letter in mid to late March.”
It also listed by name the one specific scholarship applied for , which we don’t recall selecting, and which is no better than the Presidential Elite or National Merit Finalist Package anyway.
So, it would appear, departmental awards (like the engineering one) are not tied to submitting the additional scholarship application. It would also appear there was no point in submitting the extra scholarship application for DP Jr.
Still outstanding, can departmental scholarships be stacked, although they answer there appears to be “no”.
