We told our kids 8 semesters, then parents out. So nothing was off the table- but none of my kids ended up doing a semester or year abroad. For one, it would have added a semester to fit in the required courses (too hard to get the sequencing right in the sciences at an overseas program). For another, it would have delayed thesis research, professor going on sabbatical, that sort of stuff.
But one got a fellowship for a summer research job overseas which was fantastic (and didn’t cost us anything). And there could have been more of that if the kids had been interested.
So check on the sequencing in addition to the credits. Some courses are a “fall semester 1, spring semester 2” sort of deal, so if you miss one of the semesters, you are waiting an entire year to get it on your schedule.
