Forget about this kind of school or that kind of school.
In order to assure enough desks and chairs for upcoming 9th grade girls over the next couple of years there is a need for 3 complete parallel 9th grades of 30 girls each to open up in 2009-2010. Then again another 3 parallel 9th grades in 2010-2011 etc. etc. for the next 5 years.
This problem isn’t going away any time soon.
