Students embraced and shrieked with delight after tearing open their envelopes on Thursday (August 25) morning, as the nervous wait for their GCSE results finally came to an end.
Their joy was matched by the delight of staff, whose hard work was rewarded by seeing the jubilation on their pupils' faces.
Many schools this year chose to highlight their Progress 8 score - a new indicator introduced to show how much progress students have made.
According to the measure, average results at some schools were nearly a grade higher than expected based on students' attainment when they joined from primary school.
The Heathland School, Hounslow
At The Heathland School in Hounslow, a third (33%) of all GCSE grades awarded were A*s or As.
The school had 24 pupils with at least 10 As or better, and 14 with straight As or A*s.
Deputy headteacher Michael Rose said: "We're delighted with the results. We had lots of students achieving the top grades and there was excellent progress made across the year group."
The students with 10 or more A* or A grades were: Nishi Acharya, Alvina Ahmed, Amrit Dhami, Nyla Drisdale-Gordon, Naincy Gajera, Mohammad Hakimi, Isabel Harvey, Janithaa Jeyakumar, Fatima Khan, Minhaj Mahim, Mahnoor Mustafa, Sasha Phull, Naveena Pranavarooban, Hannah Raja, Malaika Riaz, Kajal Sandhu, Sharaz Shahzad, Rohan Sood, Prashasti Tiwari, Kristen Treeby, Sarmpavi Uthayakumar, Ashley Vijayakumar, Rovena Walichchoru Evayage and Flora Waller.
For many students, the results came with the added bonus of a reward from their parents - from money to a slap-up meal or even a new pet.
Gursimranjit Dhillon, who bagged four A*s and five As, said: "I'm going to go home and nag my parents to give me something as a reward.
"I really want a dog, so these results might help me persuade them to get me one, but the main thing is that I'm not going to get kicked out of the house for failing!"
Alexander Apetroaie was offered £10 by his parents per A or A* grade, and it proved a costly decision as he bagged seven of the top grades. "That's £70. Not bad," he said.
Kaveen Sandhu didn't have to wait for her results to get a reward, with her parents buying her a rag doll cat, which she has named Captain, earlier in the week.
"I got Captain the other day as an early reward, but we'll probably celebrate with a family dinner tonight," she said.
Nando's, meanwhile, was the place to be when it came to celebrating with friends. Many students said they were heading to the restaurant to toast their success with lashings of PERi-PERi sauce.
