Summarize the following text. Accessibility to higher education implies that students get the opportunity to get university education and sufficient support from educational institutions. Increasing enrolment at the secondary and higher secondary level puts pressure on higher educational institutions. But due to limited capacity, only a small number of students may be enrolled in universities. Thus, each year a large number of students are denied access to higher education. Also, due to poverty and increase in educational expenses, students of the lower middle class do not get easy access to higher education. Moreover, those who get places in the universities have limited access to avail all kinds of diversified educational facilities relating to their study fields. Only about 12% of graduates enter higher educational institutions. More than 80% of these students are admitted to NU affiliated colleges. Others are absorbed by the public and private universities. In the last two decades, there has been a substantial rise in the number of students in private universities. According to the UGC Annual Report 2010, the number rose from 88,669 in 2005 to 2,00,752 in 2010.
