Dans le programme du Bac SMB
English carries a coefficient of 2 in the Bac Sciences Maths B (SMB) stream, level with Philosophy. Mathematics dominates the stream (coefficient 9), followed by Physics-Chemistry and Engineering Sciences (coefficient 7 each), so English can look marginal — but it and Philosophy form the narrow margin where rankings and honours are actually decided. Reading, language and guided writing are all assessed.
À l'épreuve
Three parts: Reading Comprehension, Language, and Writing (a guided text of about 180 words). SMB candidates, trained to be rigorous and systematic, do well on the Language section if they treat each grammar point as a rule with a fixed structure; the risk is a dry essay that ignores vocabulary range and register, which the Writing section also scores.
Objectifs d'apprentissage
- Apply this grammar point accurately in the Language section and in the guided writing of the Bac SMB English exam (coefficient 2)
- Form and distinguish the zero conditional (general truth) and the first conditional (real future possibility)
- Form the second conditional for a hypothetical or unlikely present situation
- Form the third conditional for a regret or a hypothesis about a finished past fact
- Never use will in the clause introduced by if
Notions clés
Zero and first conditional
Second conditional (unreal present)
Third conditional (unreal past)
Erreurs fréquentes
Putting will in the if-clause: “If it will rain” is wrong — use “If it rains”.
Confusing the second and third types: the second is about the present / future (if + past simple), the third about a finished past fact (if + past perfect).
Forgetting have in would have + past participle in the third type: “would passed” is wrong — use “would have passed”.

Questions fréquentes
How do I recognise which conditional type to use?
Ask first whether the situation is real / likely (first), purely hypothetical in the present (second) or a regret about a past fact that has already happened (third). The tense in the if-clause (present, past simple, past perfect) follows directly from that choice.
Can I mix the second and third conditionals?
Yes, in a “mixed conditional” (outside the strict programme but sometimes accepted): if + past perfect, would + base form, for a past regret with present consequences. The Bac focuses on the four classic types.
was or were after if I in the second conditional?
Both exist in speech, but were (“If I were you”) is the form expected in Bac writing, treated as more carefully correct for all subjects.
A maths-stream student often dislikes English — how do they raise the mark?
Treat it as structure. Every writing task = introduction + argument + counter-argument + conclusion; every grammar point = one rule + one correct example + one typical mistake. Memorise that framework, apply it to the 31 chapters with two example sentences each, and 12/20 is reachable without eating into the heavy maths programme.
Is this grammar point actually tested on the Bac SMB English paper?
Yes — in the Language section as gap-fill, sentence-joining or error-correction, and indirectly in Writing, where the same structures decide whether a sentence is marked as accurate. One rule, two examples and one typical mistake per point is enough to cover both.
