Tens of thousands of students are facing a scramble for university places after ministers in England, Wales and Northern Ireland performed a U-turn on A-level grades. On Monday, Education Secretary Gavin Williamson relented in the face of deepening anger and announced that grades could now be based solely on teachers' assessments, rather than being adjusted by a controversial algorithm. 

About 40% of A-level results were downgraded by the algorithm - here's why - with bright children from disadvantaged schools especially penalised. The U-turn means teachers' assessments will also be used for GCSE results, due to be published on Thursday.

Universities are seeking urgent clarification from the government as they consider their obligations to pupils who originally missed out on their first choice. Institutions are warning there's a limit to what they can do because of restrictions on space and teaching capacity, especially in a time of social distancing.

We've answered some of your questions on the climbdown and spoken to some of those young people who've suffered so much upheaval. It's still unclear what's going to happen to those studying for vocational qualifications, known as BTecs - find out more on those.

Former First Lady Michelle Obama has urged Americans to vote for Joe Biden "like our lives depend on it" at November's presidential election. She addressed the country as part of a four-day, all-virtual Democrat convention, which is kicking off two months of frenetic campaigning.

In a scathing attack, Mrs Obama said Donald Trump was "in over his head", especially in the fight against coronavirus. That accusation was reinforced by another contributor, Kristin Urquiza, who blamed President Trump for her father's death. BBC North America reporter Anthony Zurcher said Michelle Obama may insist she hates politics, but she's a natural at it.

Find out what else to look out for at this very unusual convention, and more about what Joe Biden is promising to do if he wins in November. We also have a really simple guide to the election which is good place to start.

With about nine million dogs in the UK, many people rely on a host of services to look after their pets. However, there have been cases of animals harmed by those hired to provide them. That's why the RSPCA is calling on the government to introduce licensing for dog walkers, groomers and trainers in England. Currently there is no national regulation. Some local authorities do require individuals to hold a licence, but the RSPCA describes the situation as a postcode lottery.

Reaction to the government's U-turn over exams is excoriating. "Another fine mess" is the Daily Mail's headline, under a depiction of Boris Johnson and Gavin Williamson as Laurel and Hardy. "Why is the education secretary still in a job?" the paper asks. The Daily Star puts it bluntly, demanding the PM "sack the clown". The Sun gives Mr Williamson "an F for farce". But the Guardian believes his job is safe for now. One reason is the seriousness of the challenges facing the education sector in the coming weeks, particularly the plan to get all primary and senior school children back to the classroom. Elsewhere, a number of papers take stock of the continuing protests against the recent election in Belarus. For the Times, the courage of Belarusians who have protested against Alexander Lukashenko's ballot-rigging is extraordinary and the paper says they need to know Western democracies are on their side.
