The phones began ringing off the hook at Piero Tintori's company Better Examinations back in April.
His tech business allows tens of thousands of students to remotely sit exams at the same time, with each needing just a laptop, a webcam and an internet connection.
The firm's software uses machine learning (ML), an advanced form of artificial intelligence, to detect patterns in user behaviour that could indicate attempts to cheat. Its technology can also automatically mark multiple-choice answers and mathematics exams.
In addition, it checks each exam-sitter's identity using the webcam, to ensure that no-one else is sitting the test for them. The Better Examinations program also temporarily restricts access to the internet, or certain websites and applications on each person's computer.
"We had 60 organisations from all over the world contact us out of the blue, who wanted to run exams online in May and June," says Mr Tintori. "Everything from universities, to professional organisations, to schools."
With the firm's headquarters in Dublin, plus offices in the US, Australia and Poland, it uses Amazon's cloud computing system Amazon Web Services, to allow everything to work online.
Mr Tintori says he was also contacted directly by five governments (whom he declines to name), who were keen for school exams to go ahead.

Better Examinations is just one example of the increased use of ML in response to this year's pandemic, with the technology being used to do work far more quickly than humans, such as marking exam papers.
But what exactly is ML? It is a method of data analysis, whereby computer algorithms are used to speedily process vast amounts of data, to make predictions, identify patterns and replicate actions that humans do in their day-to-day jobs.  pgslot
The use of ML is expected to grow so much over the next four years that its estimated global economic value is expected to rise from $7.3bn (?5.7bn) this year, to $30.6bn in 2024, according to one study.
