The 13-year-old dancing sensation, who won the final of Britain's Got Talent as part of Diversity, returned to Gable Hall School, Stanford-le-Hope, Essex.
He told the Sun: 'I loved every minute of it, especially being off school. Dancing in front of millions, a live audience and TV cameras beats English lessons any day.
'I'm loving all the attention we are getting, especially from the girls. I just got a massive hug from a pretty girl in my year. It's so much fun.'
Headmaster John King said: 'Perri is an inspiration to other young people and epitomises what the school is about.'
