CUG meaning in Academic & Science ?

Three national rankings of universities in the United Kingdom are published annually – by The Complete University Guide, The Guardian and jointly by The Times and The Sunday Times. Rankings have also been produced in the past by The Daily Telegraph and Financial Times.

The primary aim of the rankings is to inform potential undergraduate applicants about UK universities based on a range of criteria, including entry standards, student satisfaction, staff/student ratio, academic services and facilities expenditure per student, research quality, proportion of Firsts and 2:1s, completion rates and student destinations. All of the league tables also rank universities on their strength in individual subjects.

Each year since 2008, Times Higher Education has compiled a "Table of Tables" to combine the results of the 3 mainstream league tables. In the 2021 table, the top 5 universities were the University of Cambridge and the University of Oxford (joint first), the University of St Andrews, the London School of Economics and Durham University.
