The 4 costliest mistakes
Reciting a memorized speech
The jury evaluates living speech, not recitation.
Picking a textbook question
You need a genuine, debatable problem — not a course summary.
Ignoring time management
Time every rehearsal: 10 minutes is about 1,200-1,400 words at a natural pace.
Neglecting the discussion
The 10-minute discussion weighs as much as the presentation.
The discussion is won on precise knowledge

How does the oral exam work?
After 20 minutes of preparation, you deliver a 10-minute standing presentation on one of your two questions (chosen by the jury), followed by a 10-minute discussion with two examiners.
What is the exam coefficient?
Coefficient 10 in the general track and 14 in the technological track — one of the highest-value exams of the bac.
When is the 2027 oral exam?
The 2027 oral exam is scheduled from June 21 to June 30, 2027, pending official confirmation.
How many questions must you prepare?
Two questions, built during the year with your teachers and grounded in your specialty subjects. On exam day, the jury picks the one you present.
Can you use notes?
No: the presentation is delivered standing, without notes. You may hand the jury a visual support prepared during the 20-minute preparation time.
How to choose a good question?
A good question is debatable, grounded in your specialty curriculum, narrow enough for 10 minutes, and genuinely interesting to you.
