graduate degrees. Most of the private schools in major cities like Karachi, Lahore, Faisalabad, Hyderabad, Islamabad and Rawalpindi have co-education systems but all public schools adhere single-sex education. In some cities, single-sex education is preferred, like Peshawar and Quetta, where many schools are single-sex educational. However, there are also schools in the urban areas which are coeducational. Most colleges are also single-sex education institutions till graduation, but many private and public sector universities have coeducation systems. There are some women's universities in Peshawar and Rawalpindi as well. However, most of the higher education in Pakistan is coeducation. Saudi Arabia All schools are sex segregated, there are only boy or girl schools. The first private formal school for girls, the Madrasat AlBanat A1Ahliah was established in 1941. Sweden Around 1800, girls' middle-secondary schools begun to appear, and become more common during the 19th century. By the mid 1970s, most of them had been scrapped and replaced with coeducation. By law from the 1570s (Swedish Church Ordinance 1571), girls, as well as boys, were expected to be given elementary schooling. The establishment for girls' schools was left to each city's authorities, and no school for girls was founded until the Rudbeckii flickskola in 1632, and that school was an isolated example. However, schools for boys did accept female students at the lowest levels and occasionally even at high levels: Ursula Agricola and Maria Jonae Palmgren were accepted at Visingsö Gymnasium in 1644 and 1645 respectively, and Aurora Liljenroth graduated from the same school in 1788. During the 18th century, many girls' schools were established, referred to as ('Mamsell school') or ('French pension'). These schools could normally be classified as finishing schools, with only a shallow education of polite conversation in French, embroidery, piano playing, and other accomplishments, and the purpose was only to give the students a proper minimum education to be a lady, a wife, and a mother. In the first half of the 19th century, growing discontent over the shallow education of women eventually resulted in the finishing schools being gradually replaced by girls' schools with a higher level of academic secondary education, called "Higher Girl Schools", in the mid-19th century. At the time of the introduction of the compulsory elementary school for both sexes in Sweden in 1842, only five schools in Sweden provided academic secondary education to females: the Societetsskolan (1786), Fruntimmersföreningens flickskola (1815) and Kjellbergska flickskolan (1833)
