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
- Reuse this vocabulary field in the Bac SMB Reading answers and in the argumentative essay (coefficient 2)
- Recognise the most common negative prefixes: un-, dis-, im-, in-, ir-, il-, non-
- Form a noun from an adjective or a verb with suffixes (-ness, -ity, -tion, -ment)
- Form an adjective from a noun or a verb with suffixes (-ful, -less, -able, -ive)
- Form an adverb of manner by adding -ly to an adjective
Notions clés
Negative prefixes
Noun suffixes
Adjective and adverb suffixes
Erreurs fréquentes
Using the wrong negative prefix by false analogy: “inresponsible” is wrong — use irresponsible (ir- before r).
Confusing -ful and -less, which have opposite meanings: hopeful (full of hope) vs hopeless (without hope) — one letter changes the whole meaning.
Forming an irregular adverb as if it followed the general rule: good → goodly does not exist; the correct adverb is well.

Questions fréquentes
How do I guess the meaning of an unknown word from prefixes / suffixes in the exam?
Spot the known root (for example “legal” in illegal), then identify the prefix (il- = negation) or the suffix (-tion = noun) to work out the meaning and the word class, even without knowing the word.
Is there a single rule for choosing between un-, in-, im-, il-, ir-?
No absolute rule, but a useful tendency: ir- before r, il- before l, im- before b / m / p, in- otherwise, and un- with many Anglo-Saxon adjectives (happy, fair, kind) rather than Latin ones.
Do -ful and -less apply to every noun?
No, they are productive but not universal: some pairs exist (hope / hopeful / hopeless, care / careful / careless) while other words have only one usual form — when in doubt, check rather than guess in the exam.
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.
How do I use this theme in the Bac SMB essay without sounding generic?
Anchor each key term in one concrete, personal example — a place, a person, a situation you know. A specific illustration in accurate English scores better than a long list of terms with no support, on any of the society prompts in the programme.
