Preparing the maths speciality Bac without redoing everything.
Première and Terminale, chapter by chapter. First learn what is solid, then work on what isn’t, in the order the concepts build.
Syllabus and exam format should be checked each year on Eduscol.
One lycée question, now
Expand and simplify: (x + 3)(x − 2).
Your answer
The key chapters, and the trap in each.
At the Bac, marks are lost on choosing the strategy and ordering the steps of a proof, rarely on the arithmetic.
Quadratics
Trap: forgetting to check the sign of the discriminant before concluding.
Differentiation
Trap: differentiating a product like a sum.
Sequences
Trap: confusing arithmetic and geometric growth in a word problem.
Limits and continuity
Trap: treating an indeterminate form as a result.
Log and exponential
Trap: applying ln to each term of a sum.
Binomial distribution
Trap: not justifying the Bernoulli conditions.
