Education at Harvard has changed a lot over its history. Charles Eliot, president of Harvard from 1869-1909,made the biggest changes. For example,before Eliot was president,students didn't take entrance exams. Today, thousands of students want to study at Harvard but only about 10% of them pass the entrance exams.
Harvard is not all about education. Sport and culture are also very important. Twenty-first-century students work hard and play hard.
