PAU Chemistry (Aragón) exam-day guide
PAU Chemistry (Aragón) · Prepare for the day ahead.
Your checklist
Official ID document
Bring the identity document (DNI, passport, or equivalent) that matches the name on your registration. If you are unsure which documents the venue accepts, confirm with the provider before exam day.
Exam admission/registration proof
Print or download any confirmation, seat assignment, or call letter issued by the organizing institution. The exact document required varies by convocatoria, so confirm with the provider.
Blue or black ballpoint pens (at least two)
Written answers in the PAU are normally completed in ink. Carry spares so a failing pen does not cost you time.
Pencil, eraser, and sharpener
Useful for rough work, diagrams, and any multiple-choice answer sheet that requires pencil marks. Confirm with the provider whether pencil is permitted on the answer sheet.
Approved calculator
Check the current Aragón PAU rules on which calculator models are allowed for Chemistry. Programmable or graphing models may be restricted, so confirm with the provider and with your school before relying on one.
Simple drawing instruments
Ruler, set square, and protractor are commonly useful for graphs and geometry-style items. Verify the permitted list with the provider if in doubt.
Wristwatch (non-smart)
Exam rooms do not always have a visible clock. A basic watch helps you manage the time; smartwatches are normally prohibited.
Clear water bottle and a light snack
Stay hydrated and keep energy steady. Check venue rules on bringing drinks into the room.
Know the venue, room, and start time
Confirm the exact building, room, and reporting time in advance. Arrive early enough to find the room without rushing.
Review the periodic table and constants provided
The PAU Chemistry paper usually includes a periodic table and a data sheet. Practise using them so you do not waste time decoding them in the exam.
Leave smart devices at home or switched off
Mobile phones, smartwatches, and other electronic devices are normally banned from the exam room. Confirm the provider's policy on storage.
Plan transport and a backup
Identify a backup route or a person who can help if transport fails. Allow a buffer for delays.
Plan the day
Finish your content review and switch to timed practice. Work through a full past-style paper under exam conditions, then mark it strictly and list the three topics that cost you the most marks. Spend the remaining days on those topics only, plus a short daily review of formulas, units, and common calculation errors.
Re-read the official instructions for the Chemistry paper: number of questions, choice structure, and time allowed. Confirm with the provider if anything in the instructions is unclear. Prepare your materials bag and check the calculator's batteries or solar cell.
Do a light review only: key equations, stoichiometry steps, equilibrium and acid-base relationships, organic functional groups, and redox balancing. Pack your ID, pens, calculator, and any permitted instruments. Check the venue location and travel time. Go to bed at a normal hour rather than studying late.
Eat a normal breakfast, arrive at the venue with time to spare, and avoid last-minute cramming of new material. Skim only your own summary sheet. Switch off and put away your phone before entering the room.
Read the whole paper before writing. Note the choice structure, mark the questions you will answer, and allocate minutes per question. Write your name and identification as instructed.
Answer the questions you are most confident about first to secure marks, then return to harder items. Show working and units clearly, since method marks are often awarded. If you get stuck, move on and come back. Reserve the final ten minutes to check calculations, significant figures, and that every chosen question is answered.
Do not linger on the paper or compare answers in a way that unsettles you for the next exam. Note any topics that felt weak for future study and rest before your next sitting.
Rules to check
Bring the identity document required by the convocatoria and keep it on your desk if instructed. If you are unsure which document is accepted, confirm with the provider.
Follow the invigilator's instructions at all times, including on seating, start and finish times, and when you may leave the room.
Electronic devices such as mobile phones and smartwatches are normally prohibited in the exam room. Confirm the provider's policy on devices and storage before exam day.
Use only the calculator and instruments permitted for the Chemistry paper. If the allowed list is unclear, confirm with the provider before the exam.
Write your answers in the format the paper requires, showing working and units where relevant. Marks are commonly awarded for correct method, not only the final answer.
Breaks and permission to leave the room during the exam are usually restricted. Ask the invigilator if you need to leave; do not assume a break is allowed.
Any suspicion of misconduct, such as unauthorized materials or communication, can lead to invalidation of your exam. Keep your desk clear except for permitted items.
Scoring and grading rules for the PAU are set by the organizing institution and may change between years. Confirm the current rules with the provider rather than relying on older information.
