Josefina Rodriguez graduated NYU Stern School of Business with an MBA in marketing, product management and entrepreneurship. "I took the GMAT and sent in essays (including a scrapbook that I made!) to get in. I was in the part-time program so I went to school and worked as a marketing manager at a big financial firm at the same time." She's now the CMO for her own commercial real estate tech startup, WiredScore.

If you already have a master's degree, that can make getting another one easier, says Dan Vuksanovich, CMO of Gravity & Momentum. "I got my MBA from Northern Illinois University in 2010. I already had a master of music degree from The Johns Hopkins University, so getting into the program was pretty easy. The director waived the GMAT requirement. All I had to do was fill out the application."

Science

Science graduate degrees also fared well on the salary list.

● Computer science doctorate ($110,800, $140,600)

● Physics doctorate ($84,000, $131,300)

● Organic chemistry doctorate ($77,500, $126,700)

● Chemistry doctorate ($79,400, $122,600)

● Analytical chemistry ($80,000, $120,000)

Other masters programs with great payback potential

The nurse anesthesia master's degree had the highest early-career salary of $140,900.

● Nurse anesthesia ($140,900, $162,800)

"I can tell you that obtaining a JD is difficult," says attorney Ronald Lieberman. After taking the LSAT, the candidate then decides where to apply. "Then the candidate has to successfully enroll in law school. Thereafter, it takes three years of really intense studying to earn the JD from the law school. During that three-year period, the candidate is constantly being pushed and challenged to learn all forms of law and to radically change the way he or she thought about issues."

Worth the effort?

Don't give up if you get rejected when you first apply to grad school, says Jake Chapman, now the vice president of strategy for Sazze. He got his JD from the University of California at Berkeley and says, "I applied right out of undergrad having taken the LSAT and receiving a good but not great score. … I attended the University of San Francisco School of Law, where I treated my classes like a job. I worked 10 hours a day and if I wasn't in class, I was in the library. I finished my year at USF at the top of my class and then transferred to UC Berkeley where I completed my degree."
