The Universities and Colleges Admissions Service (UCAS) is a UK-based organisation responsible for managing university and college applications in the UK. They are the official online admissions service for students in the UK and main services include application portals to undergraduate and postgraduate programmes, access to admissions services as well as information and advice for students. The vast majority of UK universities, institutions and higher education colleges use the UCAS service for undergraduate programmes. To apply to university, up to five courses can be chosen where then an application fee is paid. Personal details, previous education, employment details (if applicable), reference details and personal statements make up the contents of the application to be submitted. Universities then give students an unconditional or conditional offer of admission if the student meets the entry requirements and grades. Depending on the subject and university, there are four different application deadlines. All applications must be received by 18:00 UK time.
