Bac Série B Bénin common mistakes
Bac Série B Bénin · Understand the traps and how to avoid them.
In SES, the candidate writes a dissertation that piles up course definitions and authors without ever answering the question posed, so the introduction never states a problem or a plan and the conclusion introduces a new idea.
Candidates memorize chapters as lists of notions and authors and reproduce them in order, because in class they are graded on reciting content rather than on building an argument; they also fear that taking a clear position is risky.
What to do instead
Before writing, spend five minutes drafting a one-sentence problem (a tension between two facts or two possible answers) and a two- or three-part plan that follows from it; in the conclusion, answer that sentence explicitly and add no new content. Practice on past topics by writing only the introduction and conclusion first.
In SES, the candidate illustrates a mechanism only with generic phrases ('production increases', 'prices rise') and never uses numerical data, graphs, or a concrete example to support the reasoning, or uses a document without saying what it proves.
Document analysis is often treated as a separate exercise from the essay, so candidates do not learn to integrate statistics into an argument; they also lack practice in reading tables and calculating rates of variation.
What to do instead
For each paragraph, require one piece of evidence (a figure, a date, an author, or a named example) followed by one sentence of interpretation ('this shows that...'). Train on tables by computing percentages and growth rates, and always cite the source and the year of the data used.
In mathematics, the candidate applies a formula or theorem without checking its hypotheses (for example using the derivative sign to conclude on monotonicity without verifying differentiability on the interval, or using a probability formula without checking independence or equiprobability).
Revision focuses on calculation drills, and the statement of theorems is memorized as a formula rather than as a set of conditions; the pressure of the timed exam pushes candidates to compute immediately.
What to do instead
Adopt a fixed written routine at the start of each exercise: list the hypotheses, the property used with its exact name, then the calculation. When revising, rewrite each theorem of the year's programme with its conditions in a dedicated sheet and check them explicitly in every corrected exercise.
In mathematics, the candidate produces a result with no justification, skips the intermediate steps, or uses an arrow chain where the reasoning behind each equivalence is not stated, and loses points even when the final answer is correct.
Candidates believe that only the final result is graded, and under time pressure they economize on writing; in class, corrections often emphasize the answer more than the reasoning.
What to do instead
Redo corrected exercises by writing the solution as a proof: 'we know that..., therefore..., which proves that...'. Before the exam, list the standard justifications expected (continuity, intermediate value theorem, sign of a difference, etc.) and verify in practice that each line of the solution is justified by the previous one.
In French, the candidate writes a commentary that paraphrases the text or, conversely, a dissertation with no reference to the corpus, and the introduction lacks a reading project or a stated problem.
The two exercises require opposite postures (explaining a text versus arguing from literature), and candidates revise by accumulating author biographies instead of practising the specific methods of each exercise.
What to do instead
Practise the two exercises separately with timed writing. For the commentary, build a table of two columns (what the text says / how it says it) and derive a reading project from it. For the dissertation, draft the problem from the wording of the subject and attach at least one precise textual reference to each argument.
In French, the candidate makes recurrent language errors in the essay: confused endings (-é/-er, -ais/-ait), missing agreements of the past participle, and poorly constructed complex sentences with misplaced relative clauses.
These errors are fossilized from earlier years and are rarely targeted in revision, since candidates revise content rather than language; they also write long sentences under pressure without rereading them.
What to do instead
Keep an error log of your own recurring mistakes and do a five-minute targeted rereading at the end of the exam, checking only those items (past participle agreement, verb endings, subject-verb agreement). Practise rewriting your own sentences into shorter ones with one main clause each.
In philosophy, the candidate produces a dissertation that juxtaposes the doctrines of authors (a 'catalogue of authors') without a problem, or a commentary that paraphrases the text sentence by sentence without identifying its thesis and its argumentative structure.
Candidates learn philosophy as a history of ideas and lack training in problematization; they do not know how to move from a subject's wording to a tension between two possible answers.
What to do instead
Train on the wording: for each subject, write three possible answers, then show why two of them conflict to obtain the problem. For the commentary, first write in three lines the thesis, the steps of the argument, and the issue at stake, then draft the explanation from that skeleton.
In philosophy, the candidate uses notions without defining them and cites an author's name without explaining the concept or its role in the argument ('as Kant says...' followed by nothing).
Under time pressure, the reference is used as an ornament to show culture rather than as a step in reasoning; candidates also confuse knowing an author's name with mastering the concept.
What to do instead
For every reference, force yourself to write one sentence explaining the concept and one sentence saying what it contributes to the current argument. Keep a concept sheet per notion (definition, distinctions, one author, one objection) and check that each paragraph contains at least one defined notion.
In history-geography, the candidate answers a history question with a geography method (or the reverse), or writes a general course recitation without exploiting the documents provided in the subject and without organizing the answer around the wording of the question.
The two disciplines share the exam paper but have distinct methods (critique of a source and chronology in history; scales, mapping and spatial organization in geography), and candidates revise them as one block of content.
What to do instead
Identify the discipline and the type of exercise from the subject's wording, then apply its checklist: in history, date the document, identify its author and context, and confront it with other knowledge; in geography, locate at several scales, use the vocabulary of spatial organization, and produce a sketch or diagram when required.
In the foreign language (English), the candidate writes or speaks long passages learned by heart that do not answer the question, and makes basic errors (tense consistency, subject-verb agreement, missing -s or -ed) that block comprehension; in the oral, the candidate reads notes instead of interacting.
Revision focuses on memorizing model texts and vocabulary lists rather than on producing spontaneous language; the fear of making mistakes leads candidates to recite prepared content rather than respond to the task.
What to do instead
Practise answering the exact question in three or four sentences with a clear structure (opinion, argument, example), then record yourself and correct tense and agreement errors using a personal error list. For the oral, prepare only key words and practise answering unpredictable follow-up questions with a partner.
