NSSCO Chemistry (6117) exam-day guide
NSSCO Chemistry (6117) · Prepare for the day ahead.
Your checklist
Admission letter and photo ID (needs_review)
Confirm with the provider/school which ID documents are accepted and whether a printed admission letter is required. Keep both in a clear plastic sleeve so they are easy to show at check-in.
Non-programmable scientific calculator (needs_review)
Confirm the permitted calculator model with the provider. Check batteries before exam day and make sure it is not a programmable or graphing model.
Pens, pencil, eraser, sharpener and ruler
Bring at least two black or blue pens, a sharp HB pencil for graphs and diagrams, an eraser, a sharpener and a 30 cm ruler. Use pencil for drawings unless the instructions say otherwise.
Lab coat and safety glasses (needs_review)
Confirm with the provider/centre whether a lab coat and safety glasses are required for the practical paper. If they are required, bring them; if not, follow the centre's safety instructions.
Simple non-smart watch
A wristwatch helps you pace the paper without relying on a wall clock. Phones and smart devices are not allowed at the bench.
Transparent pencil case or clear bag (needs_review)
Some centres require clear containers at the bench. Confirm with the provider and keep stationery minimal and visible.
Water in a clear bottle (needs_review)
Confirm whether water is permitted at the bench. If allowed, use a clear bottle with no label.
Candidate number, centre number and bench/seat number
Note these before the exam; you will write them on scripts and answer booklets. Check that your name and candidate number are correct on all materials.
Knowledge of common apparatus and techniques
Revise the names and uses of burette, pipette, conical flask, measuring cylinder, thermometer, balance, test tubes and delivery tube. Practise reading the meniscus at eye level.
Qualitative analysis and gas tests
Revise flame tests, hydroxide precipitate colours, carbonate/sulfate/chloride tests and gas tests for hydrogen, oxygen, carbon dioxide, chlorine and ammonia. Write observations, not just conclusions.
Calculations and recording conventions
Practise mole calculations, titration calculations and percentage yield. Record to appropriate significant figures, include units, and always show your working.
Periodic table/data booklet rules (needs_review)
Confirm with the provider whether a periodic table or data booklet is provided or whether you may bring one. Do not assume you can rely on memory for relative atomic masses.
Plan the day
Confirm the venue, start time, ID requirements and equipment rules with your teacher/provider. Pack a practice bag and revise core practicals: titration, qualitative analysis, gas tests and calculations. Keep a normal sleep schedule.
Pack your bag using the checklist. Check calculator batteries. Read the centre's safety rules. Do light revision of observations, equations, units and significant figures. Prepare transport and a backup alarm. Avoid learning brand-new topics.
Eat breakfast and arrive early. Use the toilet before entering the lab. Leave phones and smartwatches outside the bench as instructed. Listen carefully to the safety and procedure briefing. Check your apparatus before starting and report breakages or missing items immediately.
Read the whole paper and note the marks and suggested times for each section. Plan which questions to do first. Write your candidate details clearly on every booklet.
Work steadily. Show all working, write observations precisely (colour, precipitate, effervescence), balance equations, include state symbols where asked, and give units and sensible significant figures. If apparatus fails, raise your hand and ask the invigilator.
Check that you have answered all questions, transferred answers to the correct booklet, and included units. Do not leave until instructed.
Rules to check
Bring the admission letter and accepted photo ID; confirm with the provider which ID is accepted. You may be refused entry without them.
No mobile phones, smartwatches or unauthorised electronic devices at the bench. Follow the centre's rules for bags and devices.
Follow all safety instructions. Wear eye protection if required, tie back long hair, and never taste chemicals or smell gases directly; waft carefully.
Ask the invigilator only about faulty apparatus, missing materials or procedure. Do not ask for help with chemistry content.
Breaks and toilet visits are usually limited and escorted. Confirm the centre's policy with the provider before exam day.
Marks are awarded for correct method, observations, calculations, units and significant figures, not just final answers. Write clearly and cross out errors neatly.
Do not remove apparatus, chemicals, question papers or answer booklets from the laboratory.
Academic honesty: do not communicate with other candidates or share apparatus during the practical. Follow instructions exactly.
