CEE meaning in Academic & Science ?

Common Entrance Examinations (commonly known as CE) are taken by independent school pupils in the UK as part of the selective admissions process at age 13, though ten independent schools do select at 11 using different test papers. They are set by the Independent Schools Examinations Board. Most of the secondary schools that use Common Entrance for admission are "public schools"; most of the schools that routinely prepare their pupils for Common Entrance are preparatory schools. Both kinds of schools are normally fee-paying, that is, they are particular kinds of independent schools. The examination papers are prepared by the board, but the scripts are marked by the schools concerned; and all other aspects of the admissions process are handled independently by each school.
