Emma Raducanu was sitting A-levels during last year's French Open - now she is sitting 12th in the world rankings as a US Open champion as she prepares to make her Roland Garros debut.
Since the fairy tale of New York, Raducanu has found wins and fitness hard to come by - just like many 19-year-olds in their first full year on tour.
But unlike most in that position, Raducanu has frequently rotated coaches and been able to attract lucrative contracts with eight global brands.
She has understandably struggled with the huge public profile she assumed so rapidly, and become more withdrawn from others on tour.
