Mathematics is typically the most time-pressured WiSo section. There is no official WU math skriptum, so treat it as secondary-school business math with formula fluency under the clock, in German.
WU’s WiSo FAQ lists Mathematik as one of three content areas alongside wirtschaftliche Grundkenntnisse and deutsches Sprachverständnis. Unlike economics, WU does not publish an official math Lernunterlage equivalent to Wirtschaft verstehen. That means your syllabus has to be built from secondary-school business math depth (the same framing BBE applicants use), with language adapted to German.
The most recent WiSo Aufnahmeprüfung had 32 questions over 2 hours: 10 Economics, 9 German reading comprehension, and 13 Mathematics. WU confirms a 2-hour, in-person, entirely multiple-choice exam at VIECON; the university may adjust the selection procedure in future years. Mathematics carried 13 of the 32 questions.

Rearranging formulas, linear and quadratic equations, systems, and inequalities, practiced fast enough that German word problems do not become translation bottlenecks.
Elementary functions and differentiation appear in business contexts (cost, revenue, optimisation). Know when a statement about a derivative or extremum is true.
Descriptive stats, elementary probability, and conditional reasoning under partial-credit scoring, where one wrong tick can erase hard-won calculation credit.
WiSo math is not only computation. Many options test whether a conclusion is forced by the stem, including carefully worded German quantifiers.
Conceptually, much of the calculation toolkit overlaps with BBE mathematics. The differences that matter in prep are language and exam-track isolation: train on German stems so exam day is not your first time parsing “mindestens”, “höchstens”, or conditional clauses under the clock. Do not use BBE English math packs as your only WiSo practice.
Full BBE vs WiSo comparison →Because each stem can hide several independent judgments, a single calculation error can cascade across options, and an incorrect tick can erase correct credit via max/f penalties. Learn the scoring rules before you grind volume.
Timed mixed sets beat endless untimed drills. Aim for the same 2-hour pressure you will face at VIECON on June 30, 2026, 10:00–12:00 CEST.
