In addition to breaking records and competing in some of the top tennis championships in the world, Raducanu was also a full-time student studying for her A-Levels in economics and math (think of these as AP-level courses). "It was a bit of an escape for me, to have another thing going alongside my tennis," she told The Sun about studying for her finals. "It's actually helped me with my on-court career as I can absorb a lot of information. On court I'm more tactically astute than some others." According to ESPN, Raducanu "aced" her end-of-year exams.
