Cultural Tip
In many Spanish‑speaking countries, pulling an all‑night study session before exams is a common rite of passage. The construction ‘pasarse la noche + gerundio’ is informal and conversational; in formal writing you might prefer ‘estudié toda la noche’. Also, note that the reflexive form adds a nuance of ‘spending (the time) on oneself’, which sounds more natural in everyday speech.
