Although higher education is positioned as a site of opportunity for young women in the UK, not all female applicants experience straightforward pathways into this arena. This paper focuses on a group of 16 high-achieving girls from working-class backgrounds who are striving for academic success, in the form of top grades and places at high-tariff UK universities. Against the backdrop of neoliberalism and postfeminism, the stereotype of an academic 'supergirl' incites these young women to construct their pathways to high-tariff universities individualistically and to invest in aspirational futures beyond where they grew up. However, this stereotype also places a heavy burden on them, as young women from working-class backgrounds, to take responsibility for their own outcomes. Using Margaret Archer's concept of 'autonomous reflexivity' to analyse the research findings, the paper shows how the girls find themselves pincered between the powerfully enabling and constraining effects of their social class alongside their academic success. It highlights complexities and contradictions of striving to be a high-achieving, working-class girl that are not currently well understood within the research literature or widening access and participation agenda.
