MATSEC IM Chemistry exam-day guide
MATSEC IM Chemistry · Prepare for the day ahead.
Your checklist
Official photo ID
Bring the original ID document required by the MATSEC Examinations Board (typically a passport or Maltese identity card). A photocopy is not accepted. Confirm the exact accepted forms and validity requirements with your school or the MATSEC Support Unit before the exam.
Statement of entry / exam timetable confirmation
Print or download your personal timetable showing the subject, paper, date, time, and venue. Check the venue and session carefully; practical sessions may be held at a different location from written papers. If anything looks wrong, contact the provider immediately.
Laboratory coat
A clean, knee-length laboratory coat is normally required for chemistry practicals. Confirm with your school whether the coat must be white and whether it must be worn over closed footwear and legs covered. Do not rely on borrowing one on the day.
Safety goggles or spectacles
Eye protection is compulsory whenever chemicals, flames, or glassware are in use. If you wear prescription glasses, check whether they are acceptable as eye protection or whether over-goggles are required. Confirm with the provider.
Approved calculator
Bring a non-programmable, non-graphing calculator with working batteries. Check the provider's calculator regulations for the current session; some exams restrict memory or communication features. Do not bring spare batteries into the exam room unless permitted.
Black or blue pens, pencil, eraser, ruler
Write answers in black or blue ink unless instructed otherwise. Use a pencil for graphs and diagrams where required. Bring a spare pen. Do not bring correction fluid unless the provider explicitly allows it.
Watch (non-smart)
A simple analogue or digital watch is useful because wall clocks may not be visible from every bench. Smart watches and any device with communication or storage capability are normally prohibited. Confirm the provider's rules on watches.
Transparent water bottle
Stay hydrated during a long practical. Labels must usually be removed. Confirm whether drinks are allowed at the bench; in many labs only water in a closed container is permitted and it must be kept away from chemicals.
Hair tie and closed-toe shoes
Tie back long hair and wear closed-toe, flat shoes. Open sandals, loose sleeves, and dangling jewellery are a safety hazard near flames and glassware. This is standard laboratory practice; confirm any additional dress requirements with your school.
Know the apparatus and reagents available
Read the practical paper's instructions and any list of apparatus and materials provided in advance, if your school circulates it. You will not be allowed to bring your own chemicals or apparatus. If no advance list is given, revise common qualitative analysis tests and titration techniques.
Plan for timing and arrival
Arrive at the venue well before the reporting time; late candidates may not be admitted once the practical has started. Confirm the reporting time, venue, and any security checks with the provider. Allow extra time for traffic and for finding the laboratory.
Confirm permitted items with the provider
Rules on data booklets, periodic tables, formula sheets, and annotated notes vary. Do not assume you may bring your own. Ask your teacher or the MATSEC Support Unit which reference materials will be supplied and which, if any, you may bring. Mark this as needs_review until confirmed.
Plan the day
Re-read the practical syllabus and the list of prescribed experiments. Make a one-page summary of qualitative analysis: flame tests, gas tests, and the reactions of common cations and anions with sodium hydroxide and ammonia solutions. Practise writing observations precisely, including colour, precipitate, and gas. Check the venue and reporting time on your statement of entry and plan your journey.
Do a timed dry run of the main techniques you will be assessed on: using a burette and pipette, reading a meniscus, weighing by difference, filtering, and heating a test tube safely. If you have access to a school laboratory, ask your teacher to watch you and correct technique. If not, rehearse the written procedure and the calculations, including averaging concordant titres and calculating percentage purity or relative formula mass.
Pack your bag: ID, statement of entry, lab coat, goggles, calculator, pens, pencil, ruler, eraser, watch, water bottle, hair tie. Check the calculator batteries. Lay out closed-toe shoes and clothing that covers your legs. Read the safety rules for the laboratory and the exam regulations on conduct. Get a full night's sleep; do not stay up revising late.
Review the mark scheme logic for practical papers: marks are often awarded for accurate observations, correct use of apparatus, significant figures, units, and a clear conclusion. Rehearse how you will record results in a table with headings and units, and how you will show calculations. Confirm with your teacher whether you may annotate or write on any supplied data booklet.
Eat a proper meal and arrive early. Wear your lab coat and closed-toe shoes; tie back long hair. Leave unnecessary valuables at home. Before entering the laboratory, listen carefully to the safety briefing and note the location of eyewash, fire extinguisher, and first-aid kit. If you feel unwell or are injured, tell the invigilator immediately.
Read the whole paper first and note the marks for each section. Set out a results table before you start collecting data. Work steadily and record observations as you go; do not rely on memory. For titrations, aim for concordant titres and show all readings to two decimal places. For qualitative analysis, record the colour of the precipitate and its behaviour on adding excess reagent. Show all working in calculations and give units. If a result is anomalous, state it and explain, rather than altering data. Keep your bench tidy and label test tubes. Watch the clock and leave time to check units, significant figures, and that every question has been attempted.
Follow all safety instructions. Report spills, breakages, or injuries at once. Do not taste chemicals or smell them directly. If you need to leave the room, raise your hand and wait for the invigilator. At the end, stop writing when told, leave apparatus as instructed, and hand in all papers. Do not discuss the paper with other candidates afterwards.
Rules to check
Bring the original photo ID required by the MATSEC Examinations Board and place it on your bench for inspection. Candidates without acceptable ID may be refused entry or reported. Confirm the accepted forms of ID with the provider before the exam.
Arrive at the venue by the reporting time stated on your statement of entry. Late admission is at the discretion of the invigilator and may not be possible once the practical has begun. Confirm the late-arrival policy with the provider.
Mobile phones, smart watches, and any other electronic devices must be switched off and stored out of reach as instructed. Unauthorised devices in the examination room are normally treated as malpractice. Confirm the provider's policy on where to leave devices.
Do not communicate with other candidates during the examination. Raise your hand if you need the invigilator. Any attempt to obtain or give unfair assistance may lead to disqualification. The provider's malpractice regulations apply.
Follow all laboratory safety rules and the invigilator's instructions. Wear eye protection and a lab coat. Report accidents immediately. Failure to follow safety instructions may result in removal from the laboratory.
Use only the apparatus and chemicals provided. Do not bring your own reagents or equipment. If you need additional apparatus, ask the invigilator. Confirm with the provider whether any reference materials such as a periodic table or data booklet will be supplied.
Breaks during the practical are normally not permitted except for medical or emergency reasons and will be supervised. Confirm the provider's policy on toilet breaks and medical needs, including whether you must apply for special arrangements in advance.
Marks are awarded for accurate observations, correct technique, calculations, and clear presentation. Show all working and use appropriate units and significant figures. Read the rubric carefully; marks may be lost for missing units or untidy, unclear answers. Confirm the marking scheme's expectations with your teacher.
