Common Mistakes

• Mistake: Using the preterite instead of imperfect subjunctive, like 'Si el precio osciló'.

  Correct: For hypothetical 'if' clauses in the past, use the imperfect subjunctive: 'Si el precio oscilara'.

  Why: The preterite describes completed actions, while the imperfect subjunctive describes unreal or hypothetical past conditions.

• Mistake: Confusing the -ra and -se forms, or using the wrong ending.

  Correct: Both 'oscilara' and 'oscilase' are correct, but ensure you use consistent endings (e.g., 'oscilaras', not 'oscilaras').

  Why: The -ra and -se forms are interchangeable in most contexts, but learners sometimes mix endings within a sentence.
