Former Apprentice contestant Alex Mills has been in Cardiff today giving advice to youngsters who have just received their GCSE results.
Those with successful results might choose further study, but figures show 40 percent of students who didn't do so well say they fear they won't be able to find a job.
Alex, who started his own business, told ITV News that students who felt disappointed with their results shouldn't see it as a barrier to climbing the career ladder.
He said: "I failed my GCSEs miserably! But I've benefitted more going into a workplace scheme and working, and then getting up the career ladder that way."
