As universities shuttered their campuses and canceled activities during Friday’s lockdown, prospective students who had come from around the country for open house visits suddenly found themselves stranded and without answers to the many questions that would influence their college decision, Boston Magazine reports. After acceptances get sent out, April is typically the final push for universities to lock in their new freshmen class by inviting them to campus through scheduled open houses. But as the manhunt began, suspending much of the travel to and from Boston and requiring that much of the city stay inside, schools with scheduled admitted students weekends, including Boston University, Harvard, Tufts, and Northeastern quickly pulled the plug on their events. To cope, Both Harvard and BU took their prospective student outreach online. Representatives and students who volunteer in the Admissions Office began posting on the BU Class of 2017 Facebook page and using the hashtag #BU2017 on Twitter, offering to answer questions for students who were either stranded in Boston or hadn’t begun their journey here yet. But it didn’t stop there.
