Every year, more than nine million students in China sit a high-stakes examination - the gaokao.
The
latest test took place on Sunday and Monday. It is the only way for
students to gain entry to university and pressure is high from parents
and the nation.
From drones to "gaokao immigrants", the BBC takes a
look at the lengths some of the more remarkable stories that have
emerged this exam season.

The gaokao is seen as a make-or-break opportunity, especially for
those from poorer families, in a country where a degree is essential for
a good job.
The exam is tightly policed, but the pressure means cheating is perhaps inevitable.
The
authorities have installed closed-circuit television in examination
halls and metal detectors at school entrances to ensure students do not
sneak in smartphones.
Beijing school officials banned students
from bringing in "computerised watches", reported Sina News, and tracked
the delivery of examination scripts to schools by GPS to ensure the
questions were not leaked beforehand.
Officials in Henan province went as far as deploying a drone carrying a radio scanner to catch cheats.

The six-propeller drone hovered over two testing centres in Luoyang city, scanning for radio signals, reported Dahe Online.
Officials
said any signals found to be concentrated in the buildings would
indicate information was being sent to devices smuggled into examination
halls. They said they did not detect any unusual activity.

But some people were caught attempting to cheat.
Inner Mongolia
school authorities disqualified 1,465 students, including the children
of several Communist Party officials, after they were found to be
illegal "gaokao immigrants", reported Beijing News Daily.
The
northern region often draws students from all over the country as its
passing grade is lower than other provinces as it is less populated.
Each province determines its own set of gaokao questions, and Inner
Mongolia's exam is seen as one of the easiest to pass.
It remains unclear how those disqualified got as far as they did without being found out.
Students
can only qualify to take the gaokao in Inner Mongolia if they fulfil
minimum residency conditions, such as having attended a local school for
at least two years.
Police also busted a cheating syndicate in
Hubei and Jiangxi provinces where people were paid to pose as students
and take the exam on their behalf.
Nine arrests were made after
the syndicate's activities were exposed in an undercover investigation
by newspaper Southern Metropolis Daily.

Among the sea of fresh-faced teens sitting the exam in Nanjing,
86-year-old Wang Xia stood out as the city's - possibly the nation's - oldest test taker.
He
is also one of the most persistent. This year marked the 15th time he
had taken the exam, after failing in all his previous attempts.
In
previous interviews, Mr Wang, who only has vocational training for
medical work, said he had always wanted a medical degree to become a
fully fledged doctor.
"I don't play mahjong, I don't have any
particular hobby, but I do love reading and learning. Others may not
support me, but I still want to sit for an exam, it's my spiritual
pillar," he said.
Local media also prominently featured disabled students taking the gaokao, hailing them as inspiring examples of dedication.
These
included a boy with muscular dystrophy and an armless boy who used his
feet to write his answers on his examination script. Both were given
extra time to complete their tests.

Officials have had to manage not just students but also anxious parents.
Some
schools set up care stations for parents as they waited outside
examination halls, setting out seats under large umbrellas and providing
water.
Stations in Beijing were equipped with emergency medical supplies in case parents had sunstroke, reported Qianlong News.
Meanwhile
the education ministry was flooded with complaints from parents in
Anhui province after students took an English listening comprehension
test in halls that had faulty speakers, reported CNR News.
About 1,200 students were eventually allowed to retake the test.
