Why: The imperfect describes ongoing or repeated actions, while the preterite describes a single, completed event.
Mistake: Confusing the present tense 'estudiamos' with the imperfect 'estudiábamos'.
Correct: Context is key: 'Hoy estudiamos' vs 'Cuando éramos niños, estudiábamos'.
Why: The forms are distinct but learners might mix them up without clear time markers.
