The fall semester is quickly coming to an end with the start of final exams. But before the start of test taking and presentations, students took part in Northeastern’s Joy and Light holiday celebration and light show at the Krentzman Quad on the Boston campus. But the festive fun didn’t stop there! Students decorated gingerbread houses at this year’s annual Gingerbread House Decorating event. And earlier in the week, students walked away with top honors at this year’s NASA BIG Idea Challenge for COBRA.
