Oxford University has topped a list of the universities with the biggest shares of 2.1s and firsts, according to data from the Higher Education Statistics Agency.
93.8 per cent of students were awarded the top two grades in 2017.
While 33.9 per cent received firsts, only 5.4 per cent received 2.2s and 0.8 per cent were awarded thirds.
The only institution that had awarded a larger share of first and 2.1s was the Royal Academy of Music, a London conservatoire.
In 2017, humanities had the highest share of 2.1s and firsts with only two per cent of finalists being awarded 2.2s and none being awarded thirds.
Students in only nine of 26 humanities subjects offered by the University received grades lower than a 2.1 last year.
Those studying Ancient and Modern History had one of the highest chances of receiving the top two grades with only four finalists awarded grades below 2.1 in the last ten years.
In Medical Sciences, no thirds were awarded last year and there only 15 2.2s meaning that 96 per cent of students received the highest grades.
This is also true of Social Sciences where only 27 students received the lowest final grades.

A spokesperson for the University of Oxford said: “We think this is a reflection of our intake comprising of students with very high levels of prior attainment.
“When this is combined with the University’s excellent teaching and facilities, it is unsurprising that our hardworking, talented students get such good exam results.”
