^^This has been my experience as well, having two kids who have attended our flagship university as PSEO students. Contact with professors is extremely limited–and TA’s just don’t seem to know their stuff or feel an obligation to post solution sets or exam scores in a timely fashion. It’s unfortunate. It’s another reason I feel really good about my kiddos attending a small school that touts its strong relationships between student and faculty and that doesn’t rely on TA’s and adjuncts to teach classes.
