The line graph illustrates changes in the admission averages for three academic programmes over a forty-year period commencing in the 1970s.
Overall, it is clear that while Science followed a consistent upward trajectory, Music witnessed significant volatility throughout the period. Arts, despite some initial fluctuations, ended the period with a moderate overall increase in successful applicant averages.
Regarding Music, the admission average started at a low of 60% in the 1970s before surging exponentially to peak at 90% a decade later. This was followed by a notable dip to 75% in the 1990s and a second peak in the 2000s. However, by 2010, the figure had plummeted to 65%, ending as the least competitive programme.
In stark contrast, Science showed steady and uninterrupted growth. Starting at 75%, it climbed steadily over three decades until it plateaued at 90% between the 2000s and 2010. Arts, meanwhile, saw an initial decline to 65% in the 1980s but recovered to reach 80% by the end of the timeline, notwithstanding a decade of stagnation between 1990 and 2000.
