We wish to correct a factual error in our letter ( THES , May 25). The universities of North and East London and London Guildhall University were not "bottom of the league" in student-to-staff ratios but among the 12 worst scores. They were the last three in efficiency, the percentage of undergraduates projected to finish on time.
