The cost of university
Students usually go to university to improve their career prospects so that they can get good jobs and earn good salaries. In the past, most students found university challenging and fun. However, many professors are worried that now, students worry most about money and concentrating in class.
The government in Britain gave students 'grants' before. A grant was money so that students could live and study. Now, there are no grants and more students are working while they are at university. However, having a job has affected their studies - 21% of students say that they don't complete their work on time because of their jobs. Around 13% of students say that they miss up to five hours of class a week because of working and 17% say they missed classes because employers made them work extra hours. The jobs that students do are often badly-paid and the working conditions aren't very good, but students can't find better jobs because they don't have the qualifications and they can't work full-time.
Working is also affecting many students' concentration. According to a recent survey, the average length of time a student can concentrate in class is just ten minutes. At first, experts thought it was because of new technology and changes in learning styles. Young people today usually only spend a short time looking at websites and they tend to read and write short texts. Experts say this is why many young people have short attention spans. However, it seems that for many students, poor concentration in class is the result of working. A third of students who have part-time jobs say they find it hard to concentrate in class because they are tired and stressed.
The results of the survey also showed that many students find it hard to set goals and make decisions about different aspects of their lives. They say school education fails to provide students with life skills and the ability to live on their own when they leave school.
