The figures released showing the pass rates from 2009 to 2012 showed that no students had failed dentistry, which is the subject with the highest pass rate, in the past four years.
That contrasts with the subject with the highest fail rate, accounting and finance - a new subject area last year - which had a pass rate of 65%. Some of the other subjects students found tough last year included finance and quantitative analysis, with a 27% fail rate, biology (25% fail rate) and mathematics (24% fail rate).
Dentistry was not the only subject in which every student passed last year, with pharmacy and software engineering also having 100% pass rates.
When asked if the figures showed some courses were too hard and others too easy, deputy vice-chancellor academic and international, Prof Vernon Squire said: ''These pass rate statistics cannot be interpreted simplistically as indicators of the degree of difficulty of individual papers. They do not take into account the nature of student cohorts in the various subject areas, variations in course content, variations in the nature of course delivery, differences between professional programmes and general areas of study, and a range of other variables all affecting pass rates.''
The fact no-one had failed dentistry over the past four years was not surprising given how difficult it was to get into the university's health sciences professional programmes.
Asked if the high failure rate of accounting and finance students was a concern, he said: ''When new courses are introduced, there will be a period of adjustment. All aspects of the course, including pass rates, are monitored to ensure the paper meets all its objectives.''
