About this exam

The Castilla y León PAU Mathematics II exam is the university-access test taken by students in the science and technology track (Bachillerato de Ciencias) who want Mathematics II to count toward their admission score. It is set by the regional university access authority for Castilla y León and is scored on the standard 0–10 scale used across the Spanish PAU/EBAU system, with the grade later weighted when universities compute admission marks for technical and scientific degrees. The paper is written and paper-based: you normally choose between Option A and Option B and work the problems by hand, showing reasoning rather than only final answers. Content follows the official Mathematics II syllabus: matrices, determinants and linear systems; vectors, lines and planes in three dimensions; limits, continuity and differentiation; integration and its applications; and probability, combinatorics and distributions. Preparation works best in that order, because later blocks reuse earlier technique. Work through the official syllabus point by point, solve past regional papers under timed conditions, and keep a written log of error types - sign slips, lost domains, unfinished integrals - so revision targets real weaknesses. The official body publishes current details of dates, structure and scoring; check its site for the figures that apply to your sitting.

What you'll study

Common questions

About Castilla y León PAU Mathematics II preparation

What is the exam format?

It is a written, paper-based test with open-response problems. You typically choose between two complete options, A and B, and solve the required number of exercises from the chosen option. Full reasoning and intermediate steps earn marks, so write clearly and justify each step rather than jumping to the answer.

How long is the exam and how many questions are there?

The administering body sets and publishes the current structure, duration and number of exercises for each sitting. These details can change, so consult the official Castilla y León university access website for the figures that apply to your year rather than relying on second-hand summaries.

How difficult is Mathematics II compared with Mathematics Applied to Social Sciences?

Mathematics II is the more demanding of the two mathematics routes. It includes three-dimensional geometry, heavier algebraic manipulation and more abstract function analysis. The calculus and linear algebra are deeper, so it rewards students who practise technique regularly rather than memorising model answers.

Can I retake it if my grade is low?

Yes - candidates may generally resit in later sittings to improve their mark, and the better grade is normally the one that counts for admission. The exact rules on number of attempts and validity of prior results are set by the official body; check its current regulations before planning a retake.

What is the order I should study the topics in?

Start with matrices, determinants and systems, because the algebra skills carry into geometry. Then do vectors, lines and planes, followed by limits, continuity and differentiation. Integration builds on derivatives, so place it next. Finish with probability, which is largely independent and can be revised in parallel if time is short.

Where do candidates usually lose marks?

Common losses come from skipping justification, arithmetic and sign errors in determinant expansion, forgetting to check domains and asymptotes, omitting the constant of integration, and misapplying the limits in integration by parts. In geometry, errors often come from not verifying that a point lies on a line or plane. Writing every step reduces these.

How should I use past papers?

Do them under timed conditions, then mark them strictly against the published solutions. Record each error by type rather than by exercise, and revisit the underlying technique. Repeating this cycle on several papers is usually more effective than rereading notes, because it exposes the specific operations you perform unreliably under pressure.

Do I need a calculator?

A scientific calculator is normally permitted, but it will not rescue weak technique: most marks come from setting up and justifying the method. Check the official instructions for your sitting, since permitted models and any restrictions are specified there, and practise working without relying on the calculator for simple arithmetic.
