I cannot agree with above comments more.
At women’s colleges, wherever you look, the leaders are all women — clubs, associations, researches, committees, school government, etc. etc.
Traditionally, these roles have been assigned to male students (although it’s changing).
At women’s colleges, students are reminded that they can take on these leadership roles without male presence and that is a huge confidence boost whereas at co-ed schools, female students might fall into secondary/assisting roles and might take it for granted or not even question about it.
