Harvard University says it has finished investigating widespread cheating in an open-book, take-home final exam, but it isn't explaining exactly what happened to the students or how many were involved.

In an email Friday, Harvard released general information about cases heard by its academic integrity board this fall.

It says overall "somewhat more than half" the cases involved students who were forced to withdraw from the college for a period of time. Of remaining cases, half the students got disciplinary probation. The rest weren't disciplined.

As many as 125 students were implicated in the exam-cheating scandal. The inquiry started after a teaching assistant detected problems, including that students may have shared answers. School officials say the spring course involved included undergraduate students at all class levels.

Some athletes became ensnared, including two basketball players who were scratched from the roster.
