Which to me seems the best way, you still have to learn throughout the year. Especially to avoid cheating this works nice. And as an aside, most people I know that did a year abroad in the US got 1-2 grades higher, as it was quite easy to just farm extra credits.
At my school, tomorrow is the last day of exams. Most of the students have left campus. There's no time or mechanism to schedule an(other) exam.
