TOLC-B syllabus
The syllabus lists all the topics, divided by section, you need to know in order to prepare for the TOLC.
The Basic Mathematics module is intended to test the student's basic preparation, which is required for all degree courses in the science area, even those that make relatively less use of mathematics. The same module can be found in both the TOLC-S and TOLC-B tests, as it provides important information for all the above-mentioned degree courses. However, it is worth remembering that the mathematical knowledge and skills that are tested in this module are only a part of those that it is good to have at the entrance to degree courses such as those in Mathematics or Physics. It is therefore suggested that those interested in such courses read the Reference Framework for Mathematics, which can be found on the Orientazione project website and which provides a more complete indication of the preparation that may be useful.
In order to answer the questions in this module, it is necessary to understand the text of the questions and answers and to reason about the information provided, using mathematical knowledge that is included in the first three or four years of the curricula of all secondary schools. The specific knowledge required is grouped in six nuclei. The general skills of understanding, representing, reasoning, modelling and problem-solving are described in three further cross nuclei. The questions are constructed in such a way that a calculator is not required, and its use is not permitted during the test. It should be noted that in a single question, there may be concepts that are indicated in the syllabus in several nuclei. The terms and symbols that are used vary from those most frequently used in school and in early university lessons.
For each core, there is a description of skills and abilities to work with the concepts that are useful for answering the questions, linking them appropriately. In the Reference Framework for Mathematics developed by the Orientazione Project, there is a more detailed description of the topics and skills indicated in the syllabus, set in a broader framework and accompanied by several examples of questions and exercises that may be useful for students to assess and possibly improve their preparation. The Reference Framework of Logic, Reasoning and Problems may also be useful for these purposes.
Numbers
In order to answer the questions involving the topics of this nucleus, it is necessary to work with numbers, with confidence and flexibility, using different representations of the numbers themselves and choosing those that are most useful depending on the situation and goals. The use of a calculator is not permitted during the test, as it is never necessary to answer the questions; instead, it is useful to be able to do simple calculations by mind, possibly helping the working memory with paper and pencil to perform elementary algorithms and to note down partial results. Among various equivalent procedures for performing calculations, it is important to choose the most efficient and simplest ones; to this end, the meaning and properties of operations and ordering must be known and coordinated. The ability to make estimates, besides being useful in itself, allows one to quickly assess the plausibility of the result of calculations and thus provides a useful control tool.
- Addition and multiplication operations between integers, fractions, decimal numbers. Sorting. Properties of operations and ordering. Subtraction and division. Concept of rational number. Representations of numbers on a line. Real numbers
- Integer division with remainder. Divisors and multiples of an integer; greatest common divisor (GCD) and least common multiple (LCM) of two or more positive integers
- Power with integer exponent of a number and properties of powers. Positive integer root of a positive number. Power with rational exponent of a positive number
- Estimates and approximations. Percentages. Calculation and transformation of simple expressions.
Algebra
In order to answer the questions involving the topics of this core, it is necessary to work with literal expressions and transform them appropriately according to the goals. Given equations must also be transformed in such a way as to obtain equivalent equations that can be solved more easily or from which the relevant information on solutions can be obtained. The same consideration applies to inequalities and systems. Knowledge of simple procedures and algorithms is important, but it is very important to recognise some simple structures that expressions can have, to see their properties and consequently to choose an effective operations strategy. A student is also expected to be able to use algebra as a tool to represent and process ideas or information, and thus to model and tackle problems in different contexts. In particular, in order to answer certain types of questions, it is necessary to translate the problem and the information provided by the text into an equation (or inequality or system); it is then necessary to transform and possibly solve the equation; finally, it is necessary to interpret in terms of the initial problem the meaning of the algebraic operations that have been performed.
- Literal expressions: manipulation and evaluation
- Concept of solution and 'set of solutions' of an equation, an inequality, a system of equations and/or inequalities. First and second degree equations and inequalities. Linear systems.
Geometry
In order to answer the questions involving the topics of this core, it is necessary to understand and use descriptions and representations of elementary geometric figures and their simple combinations, and to apply on them appropriate reasoned transformations, decompositions and recompositions. To analyse the properties of a certain geometric configuration, it is often useful to use different representations and both synthetic and analytical point of view, and to put together the information that can be obtained from the different approaches. Skills that are very useful in guiding representation and reasoning are the mental visualisation of geometric objects and the ability to imagine, when looking at a figure, even features that are not explicitly drawn but that complete it and allow one to understand its meaning.
- Most common plane and space figures (segments, straight lines, planes, angles, triangles, quadrilaterals, circumferences, parallelepipeds, prisms, pyramids, cylinders, cones, spheres), with their characterising properties and graphic representations

Equations of straight lines that are parallel or perpendicular to a given line. Intersection of straight lines and representation of the solutions of a system of first degree equations
- Distance between two points and equation of a circumference given its centre and radius.
Functions and graphs
In order to answer the questions involving the topics of this core, it is necessary to relate the information obtained from different representations of the same function; for example, thanks to the information that can be read on the graph of a function f, to determine the solutions of an inequality of the type f(x) > 0 or to establish that the value f(x) cannot be expressed by a formula of a given type. It is necessary to be aware of how the behaviour varies and how the graph of functions of a certain family changes as the parameters that define them vary. To answer the questions and to connect the properties of the different families of elementary functions, it is very useful to quickly visualise the graph of the functions x ↦ af(x), x ↦ f(x - a), x ↦ f(x) + g(x) from the graph of the functions x ↦ f(x) and x ↦ g(x). Finally, it is important to use the language of functions to express relationships between quantities describing a natural phenomenon and their variations, in different contexts.
- Language and notations for functions. Graph of a function. Composition of functions. Existence and uniqueness of solutions of equations of the type f(x) = a, invertible functions and inverse function
- Characteristic properties, graph and behaviour of the following families of functions of a real variable: power functions and root functions; polynomial functions of first and second degree; functions of the type x ↦ 1/(ax+b) with a and b assigned constants; absolute value function; exponential functions and logarithmic functions in different bases; sine function and cosine function
- Equations and inequalities expressed by functions, for example f(x) = g(x), f(x) >a.
Combinatorics and probability
In order to count the elements of a set, it is necessary to represent them in some suitable way and to have suitable systematic listing and counting strategies.
The calculation of the probability of an event is only required in the case of random phenomena for which the possible events are finite in number. In such a situation, it is necessary to find an appropriate representation of the set of events and, in this representation, an appropriate description and decomposition of the event of interest in terms of simpler events whose probability is known.
- Representation and counting of finite sets
- Disjoint events. Independent events. Probability of the union event of disjoint events. Probability of the intersection event of independent events
- Description of events in simple paradigmatic situations: tossing a coin, rolling a die, drawing from an urn. Tree diagrams
- Conditional probability.
Means and variability

- Qualitative and quantitative variables (discrete and continuous). Absolute and relative frequency
- Representations of distributions (tables, bar graphs, pie charts, histograms, ...). Mean and median.
Understanding and representing
- Understand texts that use, also contextually, languages and representations of different types
- Depending on the situation and goal, use different representations of the same mathematical object

The Physics section syllabus is deliberately limited to the fundamental knowledge expected at the end of almost all secondary school curricula and no further in-depth study is required. It is appropriate to emphasise the fundamental nature of certain mathematical skills related to the modelling of natural phenomena, in particular: i) the use of graphic representations and functional models related at least to direct and inverse proportionality, linear dependence, increasing and decreasing quadratic proportionality, sinusoidal, exponential and logarithmic dependencies; ii) the recognition of proportionality relations between quantities used in laws, both in algebraic and graphic exercises. It is also essential to know how to use: the International System units of measurement (SI), including prefixes, and the practical units most frequently used in science, scientific notation, the concept of order of magnitude, vector calculus limited to composition and decomposition of vectors and the scalar and vector product.
In order to answer the questions in this module, it is necessary to understand the text of questions and answers and be able to think about the information provided, linking it through the appropriate laws. The specific knowledge required is collected in eight thematic nuclei. The questions are constructed in such a way that a calculator is not required, nor permitted during the test. It should be noted that a single question may involve multiple concepts indicated in the syllabus in several different thematic nuclei.
Each nucleus describes the skills and abilities needed to work with physical concepts and quantities, which, if linked appropriately, are useful for answering the questions. In the "Quadro di Riferimento" (Reference Framework) for Physics, which can be found on the ORIENTAZIONE project website, a more detailed description of the topics and skills indicated in the syllabus can be found, set in a broader framework and accompanied by several examples of questions and exercises that can be useful for assessing and possibly improving one's preparation.

To successfully address the questions in this nucleus it is necessary to know and distinguish the different classes of hydrocarbons and the main organic compounds by identifying the functional group that characterises them and assigning them the correct nomenclature.
- Origin and characteristics of hydrocarbons
- Carbon hybridization
- Structure and nomenclature of the main organic compounds
- Combustion reactions
- Isomerism, relationship between structure and property
- Alkanes, alkenes, alkynes, cycloalkanes
- Benzene and aromatic compounds
- Alcohols, aldehydes, ketones and carboxylic acids.
Applied chemistry
Applied Chemistry allows us to identify, describe and predict the chemical reactions underlying the most important biological, environmental and industrial processes. To successfully address the questions in this nucleus it is necessary to know the main chemical transformations related to everyday life and environmental and sustainability issues; to know how to read and interpret a label and to know the main safety rules for handling chemical products in everyday use.
- Measurements, units of measurement and uncertainties in experimental measures
- Chemical transformations in everyday life
- Correct reading of commercial product labels (beverages, food, chemicals)
- Main environmental issues (acid rain, greenhouse effect, smog…)
- Safety regulations.
