ExploreAbout this exam
The Balearic Islands PAU (Prueba de Acceso a la Universidad) Chemistry exam, often called Química PAU Illes Balears or Selectividad Química Baleares, is the subject-specific component of the university entrance procedure for students in the Balearic Islands who want to study degrees with scientific or health-science profiles. It is aimed at students who have completed Química in 2º de Bachillerato and need to improve their admission score, as well as at candidates from other routes who must accredit chemistry knowledge. The paper is written in Spanish (with Catalan versions available) and consists of open-response problems and theoretical questions, typically organised in blocks that cover atomic structure and the periodic table, chemical bonding and intermolecular forces, kinetics and equilibrium, acid–base equilibria, redox and electrochemistry, and organic chemistry. Some blocks offer a choice between alternative questions, so reading the whole paper before starting is part of the technique. Preparation should be built on the official curriculum for Química 2º de Bachillerato: master stoichiometry and balanced equations first, then work through each block with past PAU papers from the Balearic Islands, timing yourself and writing full solutions. Because the exam rewards clear reasoning and correct units as much as the final number, practise setting out calculations step by step. Always check the current call, structure and scoring rules on the official UIB and Balearic Government websites, since these details are published each year and are not fixed here.

About Balearic Islands PAU Chemistry / Química 2º Bachillerato UIB preparation
What is the format of the PAU Chemistry exam in the Balearic Islands?
It is a written, open-response exam. You solve problems and answer theory questions across the six standard blocks, and in some blocks you choose between alternative questions. The exact number of questions, the optional structure and the scoring are set out in the official instructions for each call, published by the UIB and the Balearic Government.
How long is the exam and how many questions does it have?
The duration and the number of items are fixed in the official exam instructions for each year, so check the current call on the UIB or Balearic Government website. Do not rely on figures from previous years, because the structure can change. Plan your timing around the official duration once it is published.
How difficult is the Chemistry PAU compared with school tests?
It is generally more demanding than a standard school test because it covers the whole 2º de Bachillerato syllabus and requires you to reason under time pressure. The level is equivalent to the official curriculum, not beyond it. Students who have practised full past papers and mastered stoichiometry usually find the difficulty manageable.
Can I retake the Chemistry PAU if I do not get the score I need?
Retake rules are set by the Balearic Government and the UIB and can change, so confirm the current policy on their official sites. In general, the PAU has more than one call per year and candidates may sit again in later calls, but the specific conditions and any limits must be checked in the current regulations.
In what order should I study the topics?
Start with atomic structure and bonding, because they underpin everything else. Then move to kinetics and equilibrium, followed by acid–base and redox, which rely on equilibrium reasoning. Leave organic chemistry for last but do not neglect it, since it carries substantial weight. Finish with full past papers under timed conditions.
What are the most common mistakes candidates make?
Typical errors include unbalanced equations, missing units, confusing oxidation and reduction, misapplying Le Chatelier's principle, and forgetting to state assumptions in pH calculations. In organic chemistry, students often misidentify functional groups or ignore isomerism. Many also lose marks by not reading the optional questions carefully before choosing.
Do I need to memorise formulas and constants?
You should know the standard formulas and be able to use them fluently. Some constants and data may be provided in the exam, but you cannot rely on that. Check the official instructions for what is supplied. Practising without a formula sheet and then with one is good preparation.
Is the exam available in Catalan?
The Balearic Islands are bilingual and exam papers are normally offered in Catalan and Spanish. The exact language options are stated in the official call. Answer in the language of the paper you receive, and make sure your terminology is consistent, especially for functional groups and laboratory terms.
How is the Chemistry PAU scored, and what score do I need?
Each question carries a weighting given in the official instructions, and the total is converted to the PAU scale. The pass mark and the contribution of Chemistry to your admission score depend on the university and degree you are applying for. Check the current UIB admission rules for the exact figures.
Where can I find official past papers?
Past PAU papers and model exams are usually published by the UIB and the Balearic Government on their official websites. Use only those official sources for structure and wording, and supplement them with your own textbook and class notes. Avoid unofficial compilations that may not match the current syllabus.
