Probably depends heavily on the circumstances. If the student is a first year, fourth year, is job seeking, extrovert and/or has many classes and activities that don’t lend themselves to online learning (performing arts, some discussion groups, labs) it would be very reasonable to postpone since the experience isn’t equivalent.
My son is fortunate(?) that he’s already established a good friend group, his classes work well online (mostly computer and math) and as an introvert he probably already thinks it’s exhausting to keep up with the friends he has, feels no need to seek more. So for him, online learning another quarter wouldn’t be a problem at all. He’s finding it’s working well and the teachers are organized and beyond helpful. He also was offered a great internship that he can do remotely for the next six months. But I know that’s not everybody’s experience and it’s not the full college experience. It’s only working for him because he was already established in his groove at UChicago, his classes are a type that works online and he’s not graduating or seeking jobs.
