She got into Harvard.
Literal
She [topic-は] Harvard-univ [into-に] enrolled.
ハーバード大 abbreviates ハーバード大学 by clipping 学; this 大 ('university') is a productive shorthand on university names — 東大 (Tokyo University), 京大 (Kyoto University), 早大 (Waseda), and so on. 入学する ('to enrol in school') takes に for the institution, paralleling 入る ('enter'); the related 卒業する ('graduate from') takes を for the institution being left behind. Getting into a top university is a major life event in Japan, where 受験戦争 ('exam war') describes the high-stakes competition for elite school admission, and a name like Harvard carries strong prestige despite — or because of — being foreign.
