Castilla y León PAU Business and Business Model Design exam-day guide
Castilla y León PAU Business and Business Model Design · Prepare for the day ahead.
Your checklist
DNI or valid ID document
Bring the original national identity document or passport. Confirm with your school or the tribunal which documents are accepted, since rules can vary by call.
Printed exam schedule and room assignment
Check the official PAU calendar for Castilla y León and your assigned seat/room. Confirm the exact timetable with your centre; do not rely on memory.
Blue or black ballpoint pens (at least two)
Write in ink. Bring spares; pencil is normally only for rough work unless the tribunal says otherwise. Confirm any specific writing-instrument rule with your centre.
Pencil, eraser and ruler
Useful for graphs, tables and rough calculations in the business-model design tasks. Keep rough work clearly separated from final answers.
Approved calculator
Confirm with your centre which calculator models are permitted. Do not bring programmable or graphing models unless explicitly allowed.
Wristwatch (non-smart)
Exam rooms may not show a visible clock. Smart watches and phones are normally not allowed at the desk. Confirm the centre's policy.
Clear water bottle, no label
Stay hydrated during a long exam. Confirm whether drinks are allowed in your room; rules vary by venue.
Review the official exam structure and scoring
Know the number of questions, optional sections and weighting published in the official model. Do not invent a structure; check the current official document.
Prepare formula and concept sheet
One page with key ratios (liquidity, solvency, profitability), break-even, payback, NPV and business-model canvas terms. Use it only for revision, not in the exam.
Practise full past papers under timed conditions
Use official PAU models from previous calls in Castilla y León. Time yourself to the published duration and mark against the official criteria.
Check transport and arrival time
Plan to arrive well before the call time. Confirm the required arrival margin with your centre.
Confirm permitted materials with your centre
Some materials or aids may or may not be allowed. Confirm with the provider before the exam day; do not assume.
Plan the day
Do a full timed mock using an official PAU model. Focus on the business-model design section: identify the problem, value proposition, customer segments, channels, revenue and cost structure. Review the financial ratios and break-even formulas you will need. Stop learning new content; consolidate.
Build a one-page summary of formulas and definitions. Check that you can compute liquidity, solvency, profitability, break-even, payback and NPV without notes. Re-read the official scoring criteria so you know how marks are distributed.
Light review only: skim your summary sheet and the structure of a model answer. Prepare your documents, pens, calculator and clothes. Confirm transport and arrival time. Sleep at your normal time.
Eat a proper breakfast. Re-check your ID, pens, calculator and water. Arrive early. Do not try to learn new material; a quick look at your summary sheet is enough.
Read the whole paper before writing. Note the marks per question and choose the optional questions you will answer. Allocate time proportionally to marks and leave a few minutes to review.
Answer the questions you know best first, but keep the numbering clear. For the business-model task, structure the answer: problem, solution, target customer, value proposition, channels, revenue model, costs and key metrics. For numerical questions, show the formula, the substitution and the result with units.
Check that every required question is answered and numbered correctly. Verify units and that no answer is left blank where a mark is available. Make sure your name and details are filled in as instructed.
Rules to check
Bring the original ID document required by the call. Confirm with the provider which documents are accepted; photocopies or expired documents may not be valid.
Electronic devices, including mobile phones and smart watches, must normally be switched off and kept out of reach. Confirm the centre's exact policy before the exam.
Write your answers in the language and format the paper requires. Number answers clearly and follow the instructions on the cover page.
Do not communicate with other candidates during the exam. If you need to leave the room, raise your hand and follow the invigilator's instructions.
Scoring follows the official criteria for the subject. Show your working for numerical questions; partial credit is normally available for correct method even if the final result is wrong.
If you believe there is an error in the paper, notify the invigilator. Do not change the question yourself or assume a correction will be announced.
Confirm with the provider any rules on breaks, food and drink, and permitted materials, since these can vary by venue and call.
