Delhi schools continue to give the city sleepless nights. For those whose kids are in good schools, there is a bad news - the schools want a whopping 30-40 per cent increase in fees by the end of this week. Parents like Pranjali is getting ready to pay a whole lot more for her children's education. Her son and daughter both attend Modern School, which charges Rs 20,000 per month. And soon, that amount is likely to climb by at least Rs 6,000.
