Why NYC students spend the summer studying for one test

Students in New York City are preparing for the "test that can change their lives" - the entrance exam for the city's top high schools.

Many spend their summer studying for the test - including at hundreds of prep centres across the city. 27,000 students tried last year and only 5,000 made it.

Anna Bressanin spoke to two groups who have given up their summer to study - the children of Bangladeshi immigrants, who typically do well on the test, and African-American students in Brooklyn, who make up only 5% of those matriculating at top schools.
