Burundi Concours National 9ème common mistakes
Burundi Concours National 9ème · Understand the traps and how to avoid them.
In French, writing a dictated or composed sentence without applying subject-verb agreement (e.g., «Les élèves de la classe travaille»), leaving the verb in the singular when the subject is plural.
Candidates often match the verb to the nearest noun («la classe») instead of the true subject («les élèves»), because Kirundi conjugation is more tolerant of this and because they compose sentences orally first and transcribe them without re-checking the grammatical subject.
What to do instead
Train a two-step check: underline the subject, cross out any complement introduced by «de», then write the verb ending. Practise ten sentences per day with subjects like «la majorité des élèves», «beaucoup de gens», «chacun des candidats» so the habit becomes automatic.
In French, confusing homophones in dictation and composition (a/à, ou/où, ce/se, son/sont, la/là, peu/peut/peux), producing sentences such as «Il à mangé sont pain».
These pairs sound identical, and candidates write by sound rather than by grammatical function; the substitution test (replacing with «avait» or «ou bien») is rarely taught explicitly in revision.
What to do instead
Memorise a small substitution grid: «à» becomes «avait», «a» is the verb; «ou» becomes «ou bien», «où» marks place; «son» becomes «mon», «sont» becomes «étaient». Apply the grid to every ambiguous word during a five-minute proofreading pass at the end of the paper.
In mathematics, solving an equation or inequality by moving terms without changing signs, or dividing by a negative number without flipping the inequality sign, giving answers like x > -3 instead of x < -3.
Candidates learn procedures as memorised gestures rather than as balanced operations on both sides, and the inequality reversal rule is easily forgotten under exam pressure because it is an exception, not a routine.
What to do instead
Require a written line showing the operation applied to both members at each step, and circle any negative divisor before flipping the sign. Solve three inequalities per session and verify each answer by substituting a test value back into the original inequality.
In mathematics, confusing perimeter, area and volume formulas, or forgetting to convert units before computing (mixing cm and m, or cm² and m²), so a rectangle's area is reported in cm or a tank's capacity in m².
Formulas are memorised as strings of letters without attaching each to a physical quantity, and unit conversion is treated as a separate chapter rather than a compulsory preliminary step.
What to do instead
Keep a one-page table pairing each formula with a sketch and its unit (length in m, area in m², volume in m³). Before any calculation, write all given values in the same unit and state the expected unit of the answer; reject any result whose unit does not match.
In biology, describing digestion, respiration or blood circulation as a list of organs without stating the order, the transformation that occurs, and the pathway of substances (e.g., saying blood goes from the heart to the lungs without mentioning oxygenation or return).
Candidates memorise isolated labels from the textbook diagram and reproduce them in any order, because they revise by rereading rather than by reconstructing the process aloud or in a drawn diagram.
What to do instead
Redraw each system from memory as an arrow diagram (organ → substance entering → substance leaving), then compare with the lesson. Practise explaining the route in full sentences, naming the blood type (oxygenated or not) at each stage.
In physics, writing a numerical result without its unit, or mixing the units of a formula (using grams in a formula requiring kilograms, or minutes instead of seconds) when applying v = d/t or P = m·g.
Candidates focus on getting a number and treat units as decoration; the international system is taught as a list to recite rather than as a condition for the formula to be valid.
What to do instead
Adopt a fixed layout for every exercise: data with units converted to SI, formula, substitution, result with unit, and a one-line sentence of interpretation. Deduct marks from yourself during practice whenever a unit is missing, so the reflex becomes automatic.
In chemistry, writing an unbalanced equation or confusing atoms, molecules, elements and compounds, for example writing H₂ + O₂ → H₂O without balancing, or calling a mixture a pure body.
The symbolic notation is new and abstract, and candidates copy equations from the board without counting atoms; the distinction between a body and a mixture is often reduced to a phrase learned by heart.
What to do instead
Balance every equation by counting each element on both sides and writing the count underneath, then verify. Classify ten everyday samples (water, air, salt, milk) as pure body or mixture and justify each choice by a test (single substance or several).
In history and geography, giving dates and events without causal links, or answering a map-reading question by naming a feature without locating it (no compass direction, no neighbouring reference), e.g., «le lac Tanganyika» with no position given.
Revision is done by reciting timelines and lists of names, and map exercises are skipped because they seem less examinable; candidates therefore lack the vocabulary of location and the habit of explaining causes and consequences.
What to do instead
For each major topic, build a three-column table: cause, event with date, consequence. For geography, describe every feature with a location formula (direction, boundary, neighbouring feature) and practise locating Burundi's relief, lakes, rivers and borders on a blank outline.
In éducation civique et sociale, answering with vague moral statements («il faut être sage», «c'est mauvais») instead of naming the institution, the right, the duty and the legal or social consequence involved.
Candidates treat the subject as general advice rather than as knowledge to be demonstrated, and they lack precise vocabulary for rights, duties, institutions and civic procedures.
What to do instead
Answer with a fixed structure: identify the right or duty, name the institution or authority concerned, state the consequence of violating it, and propose one concrete civic action. Rehearse this on ten situations (taxes, corruption, environment, gender violence).
In Kirundi and national culture, mixing French syntax or vocabulary into a Kirundi sentence, or misusing proverbs and idioms by quoting them out of context, and in English, translating word for word from French instead of using correct English structures.
Candidates think in French or Kirundi and translate literally, and proverbs are memorised as formulas without their meaning, so they are inserted where they do not fit; English tenses and prepositions are then copied from French patterns.
What to do instead
For Kirundi, rewrite five French sentences per day in natural Kirundi and explain each proverb's meaning and appropriate situation. For English, memorise complete useful sentences (not isolated words), practise the present simple, past simple and prepositions, and read each answer aloud to catch literal translations.
