Advisors whose clients want their college-aged children to have some skin in the game for their education may want to suggest this freelance work  and subscription service that’s enabling students to earn money and graduate on time.

Toronto-headquartered OneClass, established in 2010, hires freelance student note takers to post their class notes online and sells subscriptions that enable student to access class notes and study guides.

Students registered as official note takers (who are required to attend all classes and upload their notes within 24 hours after each class) can earn up to $470 per course, said Kevin Wu, the chief operating officer and a co-founder of OneClass. The highest earners, who concurrently take notes for four classes, earn close to $2,000 per semester.

Official note takers are paid weekly through PayPal. Other students who have “notes lying around and are looking for something to do with them,” he said, can earn $10 in cash or gift cards when they upload a semester’s worth of notes for a course.

Wu noted that close to 2.5 million students use OneClass, which has a presence at more than 400 universities in the U.S. and at universities in Canada and New Zealand. Approximately 90 percent of these students are consumers looking for content, he said, and 10 percent contribute notes and study guides. Some students wear both hats.

Content users can subscribe for a monthly fee ($40), a semester fee ($60) or a yearly fee ($120). The yearly plan, offering access to unlimited classes, is most popular, said Wu.

According to OneClass’s 2017-18 User Feedback Survey, the majority of users indicate the platform has helped them earn better grades (83.6 percent) and get into their current program (73.2 percent). Most users feel confident about graduating on time (93.3 percent of current students) or said OneClass helped them graduate on time (93.9 percent of graduates)—which can save tens of thousands of dollars. And 88.3 percent of surveyed users said they upload notes to help pay for tuition and/or student loans.

Andrea Silvera, a second-year applied mathematics major at the University of California, Davis, has been an official note taker for four classes since learning about OneClass through a Facebook group. She’s using her earnings to help pay for her tuition, she said, and it’s also made her a better student. Not only does she “need to show up and pay attention,” she said, “creating notes in such a way that other students can understand has enhanced my own understanding of the subject matter.”

OneClass, which is working to add audio and video for different types of learners, provides free access to university students with accessibility and disability issues. “These departments are often understaffed and underfunded,” said Wu, “so we want to do whatever we can to help them out.”
