It is evident that in 1990, 25% degrees were granted in medicine field, however it decreased by 10% in 2000. Besides this, the ratio of computer science and business was similar in 1990, which was a third. Whilst, an escalation of 30% was recorded in the field of business during 2000 and the proportion of computer science was a fifth in the same year. Apart from this, the percentage of law in 1990 and 2000 was15% and 5% respectively. Moving further, in 2010, 25% degrees were accounted in medicine field and the ratio of computer science was increased, that was 45%. In 2010, the percentage of law and business was similar that was 15%.
