ChildLine says the number of teenagers contacting its helpline about exam stress has risen significantly.
It says the rise is down to the growing pressure on youngsters to get high exam grades and go to university.
The number of calls to the helpline in May and June was up by 62 per cent on the same period last year.
Head of ChildLine Sue Minto said: "Young people seem to be very conscious of the fact that they need to get good grades if they want to get a decent job and earn decent money. We have got huge numbers, in comparison to a few years ago, who believe they have got to go to university.
"There is a lot more in the media about young people and how well they are doing," she told The Times.
"Clearly, they care very, very much and it is because they care so much that they put themselves under so much pressure."
A-level results will be released on Thursday, with GCSE results published the following week.
If you are struggling to cope with worrying about your exam results, call ChildLine on 0800 1111.
