These increasingly popular YouTube videos – some of which have been watched millions of times – show teenagers studying for hours on end, while sharing tips and advice about how to revise.
Ruby, whose channel is called Ruby Granger named after her hero Hermione Granger from Harry Potter, has had over 13 million views.
Among her videos are speeded-up clips of herself revising for her A-levels in English, Philosophy and Chemistry for 14 and 15 hours a day.
Introducing her Study With Me: 15 Hour Study Day film, said explains: “This is the longest study with me that I have ever filmed. I just want to quickly point out that I do not do 15 hours of studying every day.
“Usually if I’m not doing anything else that day I will do 10-12 hours of work. This isn’t always homework, sometimes I like to do extension projects.”
Meanwhile, Jade Bowler’s YouTube channel Unjaded Jade has had 10.3 million views – one of her posts shows her crying as she tells how she was rejected from Oxford University – and Eve Bennett from Revision with Eve, has had 12.6 million views.
Chris McGovern, chair of the Campaign for Real Education, said that “study tubers” can offer social support and reassurance for students who may otherwise feel isolated while revising.
He added that there is “rising panic” among teenagers about exams, and that YouTube vloggers can fuel their anxiety. “One of the dangers is that it creates a sense of hysteria, a collective hysteria,” he said.
“We need to get away from the videos, I suspect they are whipping up hysteria. Unfortunately for youngsters, they tend to whip each other up into a frenzy.”
Geoff Barton, general secretary of the Association of School and College Leaders, said that on the one hand, youngsters should be congratulated for “being innovative and using technology for something constructive”.
However, he added that children must be “protected” from “setting themselves unattainable goals” after watching “study tubers” post videos of themselves revising for hours on end.
“Mental health is such an issue for young people. People present themselves in a way that is unattainable,” he said. “It goes back to schools helping each child to think about themselves, and not that everyone can do this or should do this.”
He explained that while teachers try to give their pupils as much advice and guidance as possible, there is always the possibility that they will look elsewhere.
“You always know that youngsters can access other resources, and that the quality control of these is always slightly dodgy,” he said.
Barnaby Lenon, the chairman of the Independent Schools Council, has previously advised teenagers to spend seven hours a day studying for their GCSEs and A levels.
He advised that pupils spend 100 hours working during the Easter holidays, covering 50 topics in two-hour slots.
“Plan to work for seven hours a day most days of the Easter break. If you work for 14 days, that will be about 100 hours of revision. If each topic takes two hours to revise, that is 50 topics,” he said.
