The Lower Saxony Zentralabitur Math study guide has 3 sections and about 1,210 words.
01Calculus
Calculus practice develops the ability to move fluently between a function, its rate of change, and its accumulated total. Expect differentiation of composite, implicit and parametric forms, evaluation of definite and improper integrals, and questions that require you to justify a limit before differentiating. Chain rule: d/dx f(g(x)) = f'(g(x))·g'(x). The inner derivative is the most commonly dropped factor.

Linear algebra and vector geometry practice is about structure: whether a system has solutions, what a matrix does to space, and how lines, planes and vectors sit relative to one another in three dimensions. Reduce the augmented matrix to row echelon form; count pivots in the coefficient block (rank A) and in the augmented block (rank [A b]). Consistent iff rank A = rank [A b]. Unique solution iff that common rank equals the number of unknowns; otherwise there are n − rank free parameters.

This statistics and probability chapter explores how data are collected, summarized, and interpreted, and how probability models uncertainty. Expect measures of centre and spread, graphical displays, normal distributions and z-scores, counting-based probability, conditional probability, and critical evaluation of study design and correlation versus causation. Centre and spread: mean is sensitive to outliers, median is resistant; standard deviation measures typical distance from the mean. Range ignores the middle of the data.
