Source please for your speculations.
If you mean speculations on Jeb Bush not actually completing the coursework required for his 4-year degree, that source is my own analysis, based on the fact he worked out of the country immediately upon graduating in a bank — so, it would seem: yes, he did complete the course requirements since a bank accepted his degree though the bank was in Latin American.
But now, it seems to me: his father got him that job, and so, unlike others who get their girlfriend pregnant while in college — if indeed that is what happened, and I certainly don’t know if it did — Jeb Bush did not have to drop out. He simply cut short his college career, maybe his father got the college to hand him a degree despite not having done the coursework, and off Jeb Bush goes to Latin American courtesy of his father, to work in a bank, since: his degree is in Latin American Studies. So, now:
it doesn’t look like he dropped out, or had to drop out; it looks like: he was just such a genius he finished in only 2-1/2 years instead of 4.
But is that really what happened? That is my speculation, a question. Which scenario is what actually happened?
And my only answer is this: I would not be surprised, now, if he was missing 1-1/2 years of coursework in his degree; I don’t know if he is or not; I would just not be surprised, now, is my point.
