ExploreAbout this exam
The PAU Applied Mathematics to Social Sciences II examination is the university-entrance mathematics paper taken in La Rioja by students from the Social Sciences track who want to study degrees such as Business Administration, Economics, Law, Sociology, or Education. It is part of the general university access phase organised each year in Spain, and it assesses mathematical technique applied to economic and social contexts rather than abstract proof. The paper is a written, constructed-response exam: you solve problems on paper, show your working, and normally choose between alternative questions within each block. The syllabus runs through matrices and linear systems, linear programming, limits, continuity and derivatives with optimisation, integration and area calculations, probability and random variables, and sampling with confidence intervals. Because the weighting leans heavily on the first three blocks, algebraic fluency and clear setup matter more than memorising formulas. Preparation that works: work through the official curriculum published by the regional education authority, practise full past papers under timed conditions, and always justify each step in writing, because method earns marks even when an arithmetic slip spoils the final number. Current details on dates, structure and administrative requirements are published by the official bodies; this page is independent study material and is not affiliated with them.

About PAU Applied Math ACS II (La Rioja) preparation
What is this exam used for?
It is the mathematics paper of the university access phase for Social Sciences students in La Rioja. The grade, combined with your other subjects, contributes to the admission score used to allocate places on competitive degrees such as Business Administration, Economics or Law.
How many questions are there and how long is the exam?
The official body publishes the current structure and duration each year, and these can change, so check the convocatoria and the model paper on the official regional education website. Do not rely on second-hand figures from older years.
Is the exam multiple choice?
No. It is a constructed-response paper: you write out full solutions, and marks are awarded for correct reasoning and method, not only for the final answer. A right number with no justification can lose points, so show each step clearly.
How difficult is it compared with the first-year course?
It is broader and faster: the same ideas applied under time pressure to unfamiliar word problems. The algebra and calculus are standard, but setting up linear programming and optimisation problems from a text is where most candidates struggle. Steady practice on past papers is the most reliable way to close that gap.
Can I retake it if I do badly?
Yes, access examinations are held in more than one sitting in the same year, and you can also sit them in later years. The rules on which grade counts and how long results remain usable are set by the official bodies, so confirm the current policy on their website.
In what order should I study the topics?
Start with matrices and systems, since they underpin later work and appear in many problems. Then linear programming, then derivatives and optimisation, then integration and areas. Leave probability and inference for last: they are smaller blocks and mostly reward careful formula use and interpretation.
What are the most common ways candidates lose marks?
Not writing the setup, skipping justifications, misreading what a question asks for, and running out of time on the long optimisation problems. Errors in basic algebra, such as sign mistakes when solving systems, also cost heavily. Practise under timing and get used to checking results for plausibility.
Do I need a calculator?
A scientific calculator is normally permitted, but the exact rules on permitted models and on graphical or programmable devices are fixed by the official body each year. Read the convocatoria carefully and never bring a device that is not explicitly allowed.
Is this page official?
No. This is independent study material written for candidates preparing for the exam. It is not affiliated with, endorsed by, or connected to the university or the regional education authority. Always verify dates, structure and regulations with the official bodies.
