Before, observed it declined slightly from 2000 to 2010 were 90% and over 75%, respectively. In addition, the low comeback rate increased significantly in the last time, accounting for 100%. By contrast, computer science started with over 25% then reached approximately 75% in 1985. Afterward, fall back to the beginning.
Similarly, physics was at the second top of the ranking in the beginning, followed by the figure for physics with roughly 27%. While, it increased steadily until 1990, then hit a plateau 5 years later. Whereas, medicine surged in 1985, replacing physics become the second top participation in courses by students.
