MSI Concours d'Admission

It tests scientific reasoning and communication under time pressure. Mathematics and physics carry the most weight, but French and English sections check whether you can read, summarize, and argue clearly. History, geography, philosophy, and general culture reward broad awareness, while logical reasoning checks pattern recognition and quick problem solving.

Expect greater depth and speed than a standard school exam. Mathematics questions often combine two topics, and physics problems require multi-step calculation. The French section demands structured argumentation, not just grammar. Difficulty is relative to the cohort, so aim for mastery of fundamentals and timed practice rather than memorizing isolated facts.

Retake rules are set by the official body and can change from year to year. Check the MSI admissions website for the current policy on attempts and waiting periods. Do not assume a retake is automatic; plan your first attempt as if it is the only one, and keep official documentation of your results.

Allocate study time roughly in proportion to weight: about half your time on mathematics and physics, a quarter on French and English, and the rest on biology, history-geography, philosophy, and logic. Adjust after a diagnostic mock: if your French score is weak, add targeted reading and writing practice even if its weight is lower.

Three failure modes dominate: running out of time because of untimed practice, losing easy marks in French and English through careless expression, and neglecting lower-weight subjects that still contribute to the total. Another is memorizing without understanding, which collapses when a problem is phrased differently. Simulate full exams and review every error.

The oral phase typically confirms or adjusts your written performance, and it tests how you think aloud, defend an argument, and handle unfamiliar questions. Prepare by explaining solutions to a friend or recording yourself. Clarity and calm matter; admissions tutors are assessing reasoning, not just the final answer.

Those details are published by the official body on its website each admissions cycle. This page does not state them because they change. Always verify on the official site before planning travel, payment, or study deadlines, and be wary of third-party sites that quote outdated numbers.

Start with mathematics and physics because they carry the most weight and take longest to improve. Add French and English practice early so it becomes a habit. Then rotate biology, history-geography, philosophy, and logic in shorter blocks. Finish with full timed mocks and error review, which is where most score gains happen.

The syllabus generally aligns with a strong secondary or early undergraduate foundation, but questions may combine topics or require insight rather than routine application. Focus on understanding definitions, proofs, and multi-step problems. If a topic feels unfamiliar, check the official syllabus rather than assuming it is out of scope.
