CAPE Biology Unit 1 exam-day guide
CAPE Biology Unit 1 · Prepare for the day ahead.
Your checklist
Valid photo ID
Bring the original government-issued photo ID (passport or national ID) in the name you registered under. Confirm with the provider which ID types and names are accepted and whether a photocopy is ever allowed.
Exam entry slip / candidate number
Print or download your entry slip or candidate number if your centre issues one. Confirm with the provider and your school how your candidate number and centre number are issued and whether you must bring them.
Centre and seat confirmation
Confirm the exact venue, room, and reporting time with your school or the examining body in advance; venues for practical papers are sometimes different from written-paper rooms.
Pen, pencil, eraser, sharpener, ruler
Bring at least two black or blue pens and two HB pencils, an eraser, a sharpener, and a 30 cm ruler. Pencil is normally used for drawings and graphs; confirm any pen-only requirements with the provider.
Calculator (if permitted)
Bring a non-programmable calculator if your centre allows one for this paper. Confirm with the provider which models are permitted and whether memory must be cleared; do not assume a graphing calculator is allowed.
Plain watch
A simple analogue or digital watch helps you pace yourself if the room clock is not visible. Smartwatches and phones are not permitted at the desk; confirm with the provider how devices must be stored.
Transparent pencil case or clear bag
Many centres require stationery in a clear container. Confirm with the provider the exact rule on bags, cases, and what may be on the desk.
Water and a light snack for after
Practical papers can be long. Confirm with the provider whether drinks are allowed at the desk; if not, plan to hydrate before entry and after the paper.
Know your practical skills cold
Revise drawing and labelling biological specimens, using a ruler for scale and magnification, reading apparatus (thermometer, balance, burette, colorimeter, microscope), recording raw data in tables with units, and calculating means, rates, and percentages.
Revise the Unit 1 practical topics
Be ready on tests for biological molecules (reducing and non-reducing sugars, starch, protein, lipid), enzyme activity, membrane permeability, osmosis and water potential, and microscopy/measurement. Know the expected observations and controls for each.
Plan your timing and reading strategy
Practise allocating roughly one minute per mark and leaving time to check units, significant figures, and that every table has headings with units. Confirm the paper's duration and mark total with the provider.
Confirm special arrangements
If you need extra time, a separate room, or other access arrangements, confirm with the provider well before the exam that these are approved and in place.
Plan the day
Do a final pass over the practical topics: food tests, enzyme experiments, osmosis and water potential, and microscopy. Write out the method, expected results, and controls for each from memory, then check against your notes. Rehearse drawing and labelling a specimen with a scale bar and stating magnification.
Confirm logistics with your school or the provider: venue, reporting time, seat, permitted calculator, and any access arrangements. Check that your ID matches your registration name. Pack stationery early so nothing is left to the last minute.
Do light revision only: skim your summary of units, significant figures, and how to calculate means, rates, and percentage change. Practise two or three data-handling questions under timed conditions, then stop. Prepare clothes and stationery, set two alarms, and get a full night's sleep.
Eat a proper breakfast and arrive at the centre with time to spare. Leave phones and smart devices stored as the centre directs. Re-read only your one-page summary; do not start new topics. Use the toilet before entering the room.
Read the instructions and the whole paper, note the mark allocation and time, and start with the questions you can do confidently. Check whether answers must be in pen or pencil and where units are required.
Show working for calculations, give units and appropriate significant figures, and label every drawing and table fully. For experiments, state the independent and dependent variables, controls, and how you would make results reliable. If a question asks for observations, describe what you would see, not just the conclusion.
Check that every question is attempted, that tables have headings with units, that graphs have labelled axes, and that numerical answers are sensible. Spend remaining time on any high-mark question you left incomplete rather than re-reading finished answers.
Rules to check
Bring the original photo ID in your registered name; confirm with the provider which documents are accepted and what happens if you arrive without them.
Arrive before the reporting time. Late entry and extra time are at the centre's discretion; confirm the provider's late-arrival policy in advance rather than assuming you will be admitted.
Phones, smartwatches, and any unauthorised electronic devices must be switched off and stored as directed. Possession at the desk can lead to disqualification; confirm with the provider where devices must be left.
Do not communicate with other candidates once in the exam room, and do not look at another candidate's work. Raise your hand and wait for an invigilator if you need anything.
Breaks and toilet visits are usually supervised and may not extend your time. Confirm with the provider how supervised breaks are handled for this paper.
Marks are awarded for correct biology, clear working, units, and full labelling; method marks are often available even when the final value is wrong, so always show your reasoning.
Use only permitted equipment. Confirm with the provider whether calculators are allowed and which types, and whether any apparatus or materials are provided by the centre.
Follow the invigilator's instructions exactly, including when to start and stop writing. Writing after the signal to stop can be penalised; confirm the provider's policy on this.
