Veteran graduate students say that even if a student isn't offered a job on admission, it's often possible later to find campus jobs that significantly defray the cost of tuition. Benjamin Bolger, who has worked his way through 10 master's degrees and one doctorate, said he cold-calls professors in fields he has studied before the start of a semester to see if there are any last-minute assistantship openings. He once took a tutoring job at one of Harvard's residential houses because it paid in the form of free meals. The key, says Bolger, is balance. "If you spend too much time working and skip the time you need to work on your own studies, you will be making a strategic error," he says. "You will spend a lot of time in the library, and you will spend a lot of time—perhaps more than you expect—working to support your studies. But it is all worth it."
