Concours ACCÈS common mistakes
Concours ACCÈS · Understand the traps and how to avoid them.
In the ACCÈS logic section, the candidate reads the whole stimulus and question before looking at the answer options, then answers by overall impression rather than by formally checking each option against the stated rule.
School habits reward reading for general meaning, and timed practice creates pressure to move fast. The candidate treats logic items like comprehension items, so a plausible-sounding option that quietly violates one condition of the rule gets selected.
What to do instead
Adopt a fixed procedure for every logic item: isolate the rule or constraint, restate it in symbols or keywords, then test each option against it and eliminate explicitly. Do not choose an option until you can name the exact condition it satisfies. Practise on 20-item sets with a written elimination mark per option so the checking habit becomes automatic before the timed phase.
In the ACCÈS quantitative reasoning section, the candidate attempts every calculation with full written arithmetic and runs out of time before reaching the last third of the section, leaving questions blank.
Candidates prepare on untimed exercises where accuracy is the only goal, so they never build estimation or elimination reflexes. Under the real clock, long division and full equation-solving consume the minutes that easier later items would have taken.
What to do instead
Train two speeds: untimed mastery of the underlying methods, then timed sets where you must answer with approximation, order-of-magnitude checks, or elimination of impossible answer choices. Impose a per-question cap (for example 90 seconds) and force a guess-and-move-on when it expires. Log how many items you left blank per mock to confirm the habit is breaking.
In the ACCÈS verbal and general-knowledge components, the candidate answers from personal opinion or from a single remembered keyword in the text instead of locating the passage sentence that settles the question.
The questions often use familiar vocabulary and everyday topics, which invites answering from background belief. The candidate also confuses a word that appears in both the passage and an option with evidence that the option is correct.
What to do instead
For every verbal item, underline or note the specific line in the passage that supports the answer before choosing. If no line supports an option, discard it regardless of how reasonable it sounds. For general-knowledge items, build a dated fact sheet of current economic, political, and cultural events from the months before the exam, and review it weekly rather than relying on memory of headlines.
In the ACCÈS English section, the candidate chooses answers that sound natural in spoken French-influenced English, particularly on prepositions, tense choice, and false friends, without checking the grammatical structure of the sentence.
Everyday exposure to English is mostly informal and oral, so the candidate's ear accepts constructions that are grammatically wrong in a written test. French false friends (for example 'actually', 'eventually', 'assist') are read with their French meaning.
What to do instead
Work through a targeted list of high-frequency French-English false friends and preposition collocations, and drill them in sentence-completion format. For each error in practice, write the correct rule in one line. Read the whole sentence aloud only after selecting an answer, to verify the tense sequence and subject-verb agreement rather than to judge by sound alone.
In the ACCÈS written expression or synthesis task, the candidate writes a summary that reproduces the source documents in order, document by document, instead of reorganising content around a comparison or a problem statement.
The candidate has practised summarising single texts at school and treats synthesis as successive summaries. Under time pressure, following the documents' order feels safe and requires no planning.
What to do instead
Before writing, spend five minutes building a two-column grid of convergences and divergences across the documents, then impose a plan with a short introduction stating the issue, two or three thematic parts, and a conclusion. Never structure a part by document number. Practise with a strict word count and a fixed time budget so the planning step is protected rather than skipped.
For the AST entry into the third year, the candidate prepares only the general business-culture and English components and neglects the prerequisite accounting, finance, or mathematics material expected at the end of a two-year undergraduate programme.
Applicants assume the parallel-admission test mirrors the post-bac concours and is mostly aptitude-based. They underestimate the subject-specific paper and discover unfamiliar technical content too late.
What to do instead
Obtain the official syllabus for each target school and map every listed topic against your transcript, marking gaps. Spend the majority of remaining preparation time on the gap topics with a textbook and exercise sets at the level of a second-year undergraduate course. Sit at least two full past papers under time conditions to confirm the technical depth required.
For AST entry into the third year, the candidate submits a motivation letter and CV that describe the same activities in generic terms and do not connect them to the specific programme, its specialisations, or its teaching method.
Candidates reuse one letter for every school and write about themselves rather than about the fit between their background and the target curriculum. They also underestimate how briefly the jury reads and how quickly generic statements are spotted.
What to do instead
Write a distinct letter per school that names two or three specific courses, chairs, or associations and explains, with one concrete example from your studies or internship, why they match your project. Replace adjectives with evidence: a project, a grade, a responsibility held. Have a reader check in one pass whether the letter could be sent unchanged to another school; if it could, rewrite it.
At the AST third-year oral interview, the candidate answers questions about the programme or the school's specialisations vaguely and cannot state a coherent post-graduation project with a sector and a first concrete step.
Preparation focuses on rehearsing a self-presentation and on defending past grades, while questions about the school and the professional project are left to improvisation. Candidates also fear that naming a precise project will sound rigid.
What to do instead
Prepare a short project statement with three elements: a target sector or function, a reason rooted in your experience, and a first step you can name (an internship, a specialisation, a certification). Research the school's programme in detail and prepare two questions to ask the jury. Rehearse the interview aloud with a third party who interrupts and challenges your answers.
For AST entry into the fourth year, the candidate presents a file built on first- and second-year coursework and does not demonstrate command of the advanced material expected after three years, including a substantial applied project or internship analysis.
Applicants transfer the habits that worked for the third-year admission and assume that a good overall record is sufficient. They do not realise the fourth-year jury assesses depth, autonomy, and the ability to analyse professional experience.
What to do instead
Rebuild the file around advanced coursework, a quantified internship or project contribution, and a written analysis of what you learned and would do differently. Prepare for technical questions at the level of the specialisation you are applying to. Ask a teacher or supervisor to review the file against the fourth-year syllabus before submission.
In the AST fourth-year written paper or case study, the candidate restates course concepts and definitions without applying them to the data or situation given, producing a descriptive answer where an argued recommendation was expected.
University revision rewards reproducing knowledge, whereas the fourth-year case paper rewards diagnosis and justified decisions. The candidate also runs out of time on the analysis and delivers only the introduction and theory.
What to do instead
Practise case studies with a fixed structure: identify the problem, set out the relevant evidence, propose two or three options with criteria, recommend one, and state the implementation conditions. Allocate time explicitly (for example one quarter for reading and diagnosis, half for argument, one quarter for the recommendation and conclusion). Have a marker confirm that your recommendation is visible and justified, not merely described.
Across all three admission routes, the candidate sits mock exams only in untimed conditions and never rehearses the actual sequence of papers, breaks, and orals, so fatigue and timing errors appear on the real day.
Practice is fragmented by subject, and candidates avoid full simulations because they are tiring and expose weaknesses. They also underestimate the effect of consecutive papers on concentration and on the quality of the final sections.
What to do instead
Schedule at least two full simulations at the real time of day and in the real order of papers, including breaks and a timed oral. After each, record where errors came from (knowledge gap, misreading, timing) and adjust the next week's work accordingly. Treat the simulation as the primary training event and subject drills as support for it.
