Peking University is a public institution that was founded in 1898, though it wasn't known by its current name until 1912. The university's main campus, known as Yan Yuan, is located in the Haidian District in the western suburbs of Beijing, China's capital city. University housing is available for both undergraduate and graduate students. Tuition costs are higher for non-Chinese nationals and vary by subject, with science subjects costing more. The university's academic calendar is semester-based, and students typically study four years for undergraduate degree programs, two to three years for master's programs and four years for doctoral degree programs.
