The bar chart illustrates the percentage of domestic and international students who got a second degree or better in different subjects at the major universities in United Kingdom 2009. 
According to the chart, technical-related subjects had significantly more international students than national students. Otherwise, there were fewer students from other countries than UK students in non-technical-related subjects except nursing and accountancy. As nursing as accountancy had 50 per cent international students and 50 per cent national students. 
Overall, all subjects have a plenty of international students but UK needs to find a way that more domestic students get a second degree in technical-related subjects.
