For Anuj Gupta, the summer holidays are an opportunity to study harder. Anuj is one of a small group of science students in Class 12 at Sangam Vihar's pahadi-wallah school in C Block. He hopes to become a doctor one day.
"Some times I watch tv to relax," Anuj said one afternoon, "But usually I just study, study, study." He doesn't play any sports and has few friends outside of school and his tuition classes.
"My school doesn't have a physics teacher,' Anuj said, "We didn't have one for the last few months of Class 11 either."
Instead, Anuj relies on his notes from his tuitions and a thick stack of reference books sourced from senior students.
The occasional game of Sudoku keeps his mind sharp.
Vijay, Anuj's father, drives a "share-auto". Passengers pay Rs 10 to hop on and hop off . He could use a helping hand, but Vijay takes the long view of the future. "Right now I want my sons to study and get a good job. Anuj is studying science. Why can't a poor kid become a doctor?"
On Eid this year, Naziya Naz and her family sought blessings for all they had received through the year.
Naziya is a student of commerce at the government-run pahadi-wallah school, while her brother Salman studies at a private school nearby.
For Sabiya, Naziya's elder sister, the holiday was a chance to relax after a stressful first year in a bachelor of science degree in chemistry from Indira Gandhi Open University.
Naziya and her friends know that this is the most important year of their school life, but the summer holidays offer a rare moment of joy in an otherwise stressful year.
"I want to become a chartered accountant," Naziya said, "It is a good job, and my family needs the money."
