This suggests a continuation of the?trend seen in 2016, when lower-ranked universities were squeezed by prestigious rivals in an environment in which the overall number of applicants is falling and student number controls have been removed. However, the data also appear to indicate that the most selective universities can relax their entry requirements only so far, possibly for fear of adversely affecting their league-table standing.
