Looking to take a class this summer? Your local college or university might be offering it at a discount. In an effort to boost summer enrollment, tuition discounts are becoming more common on campus. Unfortunately students aren't necessarily biting. Since year round Pell Grants were discontinued, summer enrollment has taken a big hit. That's a lose-lose since campus buildings are underutilized and studies show students who take summer courses are more likely to complete their degrees on time.
