The capital's 16-year-olds have been opening their GCSE results today.
And, although the number of top grades has fallen for a second year - London's schools had plenty to celebrate.

Pupils at Oasis Academy in Croydon opening their GCSEresults today.
Despite a prediction that results would dip this year theAcademy has bucked the trend.
Sixty four per cent of pupils gained five or more GCSE gradesA star to C while one in ten grades was an A or A star.
Exam boards have criticised the rise in the number of 15-year-olds taking GCSE exams, with 91,000 children sitting the tests a year early.
The overall GCSE A*-G pass rate also fell slightly this year to 98.8% compared to 99% last year.
The director of the Joint Council for Qualifications said "underlying factors" affected the dip in GCSE results but praised the "upturn" in the number studying modern languages.
Science was hit by the drop in GCSE results despite more pupils studying biology, chemistry and physics.
There was a drop across the board in all three sciences - in biology, 89.8% of entries got at least a C, down from 92.6% last year, in chemistry 90% of entries scored A*-C, down from 93%, and in physics 90.8% reached this standard, down from 93.2%.
The decline in results for the separate sciences is partly down to bright students switching to IGCSE courses and an increase in the number of 15-year-olds, who tend to perform less well, taking the exams early, JCQ said.
It added that a general trend of more students opting for the three sciences, some of whom will have lower abilities in the subject, may also have had an effect.
The dip in GCSE results comes amid a major upheaval in the exams system and it is thought the following issues have contributed to the fall:
- A rise in the number of pupils entering maths GCSE early or multiple times.
- A revamp in science GCSE following a 2009 report that said the courses were too easy.
- An increase in the number of pupils taking international GCSEs (IGCSE) in certain subjects.
