In French, 'science' meaning 'science' as a field of study is typically used in the plural — 'les sciences' — especially when referring to natural sciences collectively. The singular 'la science' is reserved for the literary/abstract sense (sense_02) or when specifying a particular discipline with a modifier (e.g., 'la science de l'informatique').
Elle a beaucoup de science.
Elle a beaucoup de connaissances.
Although sense_02 ('knowledge', literary) exists, using 'la science' or 'de science' to mean 'to have knowledge' is archaic and highly ambiguous in modern French — it risks being misinterpreted as 'science' (sense_01). Preferred terms are 'connaissances' (plural), 'savoir', or 'culture'.
