The given line graph depicts how the proportion of female students changed in four different courses at the university between 1970 to 2015
Overall, an upward trend was seen in most categories, with low witnessing the most dramatic rise. In addition, the highest and lowest figures are Computer science and Low at the beginning of the period respectively.
Looking at the graph more closely, From 1970 to 2015,There was a gradual increase from nearly 0% to reaching a peak of 98% in the figure for Low , but later decreased slightly to 95% and a final increase to exactly 100%. In contrast, The figure for computer science hit a peak at nearly 75% in 1990, with a subsequent remarkable decrease to the lowest point(more than 25%) at the end of the period
Regarding another course, the rate of students rose significantly to more than 25%, then overcame Physic between 1985 and 1995, before getting better at Computer science to achieve the second highest with nearly 100%. Meanwhile, there was a gradual increase to reach the third highest with more than 75% in the rate of students studying Medicine
