You’re treating Dickinson like it’s super selective. It’s not. They have accepted 40-50% of their applicants in recent years 48% this year. They publish data on “accepted students”, but the important number here is yield. Only 18% of those accepted actually enrolled in the most recent year that they report. They don’t tell you the stats on that group, which is the group with whom you’re competing for scholarships and other awards. One thing for sure is that the 18% who actually attend don’t have numbers as high as the total group who were accepted.
Look at the linked information. 89% of those attending are receiving some form of aid. 55% are receiving scholarship aid. Very few are paying sticker price. I don’t care if they admit by major. Thus student is a good candidate for admissions there. If they want him to come, there’s a chance that they’ll find a way. They have seats to fill. I’ve seen parents negotiate with colleges like Dickinson. As I said, it’s a reach, but there is a possibility here. They have to show demonstrated interest, write excellent essays, schedule an interview, and then engage Admissions/Financial Aid in conversations if accepted. Retaking SAT for higher score might help. It’s possible. Not trying to raise unrealistic expectations, just saying possible.
