<p>I'm currently attending a school with a 4-1-4 calendar and I'm looking at schools that have quarters, trimesters, or semesters. Does this mean that the classes I took for an entire year will end up being, say, 2/3rds of an academic year at a school with the trimester system? And does have anyone have experience with having a J-term and having schools accept/reject J-term credits? I apologize if this question has been asked already.</p>
