Saul Propp successfully passed the Physics PhD Qualifying exam, which is a multiple-day written exam covering a wide array of problems in advanced physics. All graduate students must pass this exam to continue in the PhD program, and it represents a major hurdle to advance to PhD candidacy – many don’t pass. But by studying for and taking the exam, students synthesize and unify what they have learned in their physics coursework, and gain a breadth of knowledge in multiple fields of physics, a set of theoretical tools to tackle various problems in research, and confidence to tackle physics problems that are new to them. Many students need to re-take the exam after their first summer in the program, but Saul studied hard and did great. Great job, Saul!
