If a child would like to continue on with their education or want to start a career, they can apply for college. After four years at a university or college, they will earn a bachelor's degree in one subject. Students can also choose to attend a two-year community college. Some two-year community colleges are called "Junior colleges". Colleges are not required and are not forced by local laws. Students must pay to attend college, but the price is lowered if they get a scholarship. After college, the now adult can earn a number of certificates for a career. Graduate school is another option after college. A student can earn a master's degree or Ph.D. in any subject. They may go to medical school to earn an M.D. and become a physician, law school to earn a J.D. and become a lawyer, or business school to earn an MBA.
