Great changes in higher education have given more people more opportunities to study for degrees than before. But when new graduates have job prospects, they may find many difficulties. According to the report of the Institute of Human Resources, the output of graduates in Britain has almost doubled in the past five years, and it seems that it will further increase by 57 percentage points in 2005. At the same time, the economic recession (depression) has cut back on research work. Seven-digit (14) college graduates in 2002 failed to find jobs in England, Scotland and Wales within six months after graduation. Causes many graduates to turn to graduate school as a retreat? 10 is 200 1, and the number of students in master's courses has increased by 97 percentage points. However, in mathematics and computer science courses, it increased by 149 percentage points, while in science courses, it only increased by 3 1 percentage points. The number of science students is growing and unevenly distributed, while the number of subjects is declining. "Disturbingly," said Richard Pearson, director of the Institute of Human Resources, "1995, the output of physics graduates will drop by 6 percentage points and mathematicians by 4 percentage points." Nowadays, students pay more attention to business and comprehensive non-degree courses than honorary degrees in science and single technology. No physics teacher will pay it back one day.
