IB Spanish B and ab initio · Individual oral

“Sí.” “No.” “No sé.” The three most expensive words in the IB Spanish oral.

Each one takes two seconds to say and leaves the examiner with nothing to mark.

In the oral, silence is not the only danger. A fast, confident “sí” can be just as expensive. The examiner is listening for language: range of vocabulary, tenses, structures, fluency. A monosyllable gives them none of it.

The three-step answer

Every answer, to every question, has three parts:

  1. Reaction. “¡Qué pregunta tan interesante!”, “Mmm, no lo sé todavía…”, “Ah, sí, me encantan los mercados.”
  2. The real answer. One idea, or a short list of reasons.
  3. Detail or justification. “…porque…”, “es que…”, “verás, me parece que…”.

Watch it work. Question: ¿Cuándo fue la última vez que fuiste a un mercado?

“¡Ah, pues la última vez fue hace una semana! Fui al mercado a comprar fruta para mi familia, porque nos encanta comer fruta de postre los domingos.”

Three sentences, a past tense, a connector and a personal detail. The examiner now has plenty to reward, and will probably need fewer follow-up questions.

Past, future and conditional: the tenses to have ready

Preparation questions around a photo lean on three time frames: what happened (indefinido, perfecto), what will happen (futuro, “es posible que + subjuntivo”) and what might be (condicional: “sería una buena idea…”). If a student can answer in all three, most questions are covered.

Two rules that protect the mark

  • Never switch to English. If you need time, buy it in Spanish: “Un momento, voy a pensar”, “¿Puede repetir la pregunta, por favor?”.
  • No monosyllables. A full sentence every time, even for an easy question.

A dinner-table game for the adult in the room

You can practise this without speaking Spanish. Ask a question in English, then ask for the answer in three steps: reaction, answer, reason. Then ask, “And why?” twice. The habit of expanding an answer is the skill, and it transfers into Spanish surprisingly fast.

The oral rewards a student who has rehearsed this structure until it is automatic. If you want to build it with a tutor, book an assessment lesson below.
