ExploreAbout this exam
The PAU Applied Mathematics for Social Sciences II examination is the Galician university-access test taken by students on the social-science baccalaureate track who need a mathematics score for admission. It is also used by candidates improving their access grade or switching degree pathways. The paper is written in Galician or Spanish and asks you to solve problems rather than recall facts: setting up and solving linear systems, analysing functions with limits and derivatives, computing areas by integration, working with conditional probability and the binomial and normal distributions, summarising and regressing bivariate data, and solving small linear-programming models graphically. Questions are free-response and require justified working, so method marks matter as much as final answers. Candidates typically choose between alternative problems, which rewards knowing your strengths in advance. Preparation should follow the official syllabus published by the Galician education authorities, working through past papers under timed conditions, building a formula and error log, and drilling the routine procedures (Rouché–Frobenius discussion, optimisation, Bayes trees, regression coefficients) until they are automatic. Confirm the current exam structure, dates and regulations with the official body, since these change between years.

What you'll study
About PAU Applied Math ACS II (Galicia) preparation
What is the exam format?
A written paper of free-response problems. You show full working, and marks are awarded for correct method even when arithmetic slips. Some years include short-answer or multiple-choice parts inside a problem, and you usually choose between alternative options, so read the whole paper before starting.
How long is the exam and how many questions are there?
The official body sets and publishes the current structure each year, so check its website for the number of problems, the time allowed and the choice rules. Do not rely on numbers from older papers, because the format has changed over time.
How difficult is it?
The mathematics is standard second-year social-science content, but the difficulty lies in speed and precision under time pressure. Students who lose marks usually do so through algebra slips, missing justification, or misreading what a question asks, not through unfamiliar theory.
Can I retake it, and does the grade expire?
Retake and validity rules are set by the official authorities and can change, so confirm the current policy on their website before planning. In practice, many candidates sit the exam more than once to raise their access score, and the higher grade is normally the one that counts.
What score do I need to pass?
There is no single figure to quote here: the pass mark and the grade boundaries are published by the official body for the current sitting. Check its site for the regulations, and remember that your university admission score combines this exam with your other grades.
In what order should I study the topics?
Start with matrices, determinants and systems, because the technique recurs and builds confidence. Then functions and derivatives, followed by integration and areas. Treat probability and descriptive statistics as separate blocks you revise in short, frequent sessions, and leave linear programming until last since it is quick to master.
What are the most common mistakes?
Forgetting to justify a system's compatibility before solving it, giving a derivative's sign table without stating the conclusion, omitting the constant or limits in an area calculation, confusing P(A|B) with P(B|A), and rounding regression coefficients too early. Write the formula first, then substitute.
How should I use past papers?
Do them closed-book and timed, then mark them strictly against the official solutions, noting every lost mark and why. Keep an error log by topic and revisit it weekly. Near the exam, practise choosing which alternative problem to attempt within the first few minutes.
Do I need a calculator?
A scientific calculator is normally permitted, but the allowed models and any restrictions are set by the official body, so check its current instructions. Learn to use the statistics and distribution functions on your own model before exam day rather than discovering them in the room.
Is this page official?
No. This is independent study material written to help you revise. Always confirm syllabus content, exam dates, fees and regulations with the official Galician education authorities or your school, as those details are authoritative and may change between years.
