University entrance is based on the scores achieved in the entrance examination. High school graduates need high scores to be admitted to universities. Securing a place in a public university is considered a major step towards a successful career, especially for those from rural areas or disadvantaged families. The pressure on the candidates therefore remains very high despite the measures taken to reduce the importance of these exams. In 2004, it was estimated that nearly one million students took the exam, but on average only 20% passed.
