What to expect on the Numerus Fixus (Netherlands)

Honest, no-hype information about the exam — what we know, what we don't, and how to calibrate your preparation.

Overall difficulty

High — tests advanced high-school calculus, probability, algorithmic tracing, and analytical research paper comprehension.

Question style

Multiple-choice (4 or 5 options). Calculus optimization, expected value, conditional logic, flowchart tracing, and research methodology evaluation.

Time per question

~2.5 minutes per calculus & probability problem, ~2 minutes per logic and case study question.

What this platform covers

Mathematics: Calculus differentiation, integration, curve sketching, optimization
Statistics: Normal distributions, Z-scores, expected value, combinatorics
Logic: Deductive reasoning, Modus Ponens/Tollens, contrapositives, logical fallacies
Computer Science Logic: Flowchart execution, loop tracing, graph theory, time complexity O(n)

What it does not cover

University-specific secret selection tests — institutions update annual case readings
Matching procedure motivational motivation questionnaires

Exam-day tips

1In calculus optimization problems, remember to verify local maximum vs minimum using the second derivative test.
2In deductive logic questions, watch out for the Affirming the Consequent fallacy (P -> Q does NOT imply Q -> P).
3Always attempt every question — there is no negative mark for wrong answers.
4Aim for a top 20% score to secure a low Rangnummer (Rank Number) for TU Delft or UvA Computer Science.

Community signal

Dutch Numerus Fixus candidates note that speed in calculus derivatives and logical fallacy identification is key to achieving a winning rank number.
