Teenagers across the country are sitting exams today as schools and colleges made valiant attempts to stay open despite the snowy conditions.
The "vast majority" of GCSE and A-level papers scheduled to take place were going ahead as planned, according to the exams regulator Ofqual.
While thousands of schools were forced to shut as the snow continued to fall, others were taking action to ensure that pupils could sit exams they have been preparing for over the last few months.
In some cases, schools were only opening for exam candidates.
Union leaders said schools "almost invariably find a way" to ensure that pupils can sit papers, even if it means finding an alternative venue.
A number of exams are due to take place today, including papers for A-level psychology, A-level biology, A-level geography, GCSE geography and GCSE information and communication technology (ICT).
Students who are unable to take their exams today will have to wait until the summer for the next chance to sit them, according to advice given to schools by the Joint Council for Qualifications (JCQ).
Firefighters from the London Fire Brigade are warning people to stay off the ice after they were called to rescue two men yesterday who had fallen through frozen lakes to rescue their dogs. Meanwhile, crews also rescued a child who was stuck on his sledge in the middle of a frozen lake.
Jim Knighton, Assistant Commissioner for Operational Procedures, said:
“To put it bluntly, it’s extremely fortunate we weren’t faced with a fatality yesterday. If people fall into an icy lake, hypothermia will quickly set in and they won’t survive for very long."
At midday yesterday, fire crews were called to rescue a man who had fallen into the lake on Regents Park, after his dog jumped in and vanished. Specialist rescue equipment was used to rescue the man but there was no sign of the dog. The man was treated by ambulance crews for shock and hypothermia.
Jim Knighton added:
“People with dogs should keep them on a lead and keep a close eye on them.It’s so easy for dogs to run off and end up in difficulty as we saw in London yesterday. If a pet ends up in trouble, call 999 and stay put, rather than attempting to rescue it yourself."
