Exam day, rules & kit
Can you go to the toilet in an exam? (And the other exam-day rules)
Yes, you can go to the toilet during an exam - put your hand up and an invigilator escorts you, though you usually do not get the time back. If you arrive late, go straight in: you may well still sit the paper. Leaving early is generally discouraged and often not allowed - use spare time to check your answers. Invigilators can help with practical problems, never with the questions.

Toilet trips
Needing the toilet mid-exam is allowed and completely normal. Put your hand up, and an invigilator will escort you there and back - one candidate at a time, phone-free, no detours. The catch is time: most schools do not add the minutes back (your school's exams officer sets the exact practice), so the working rule is go before you go in. But if you genuinely need it during the paper, take the trip - five focused minutes lost beats forty distracted ones. Nobody thinks anything of it.
Arriving late
Overslept, missed the bus, punctured a tyre: go straight to school and straight to the exam hall. Do not go home, and do not decide for yourself that it is too late - schools can and routinely do admit latecomers, and even significant lateness is often workable within the exam boards' rules, provided you have not seen or heard anything about the paper. For very late arrivals the school reports the timing to the board, which decides whether the script can be accepted - that is the school's paperwork, not your problem in the moment.
The only genuinely losing move is not turning up. Arrive flustered and half an hour late, and the most likely outcome is that you sit the paper and it counts. Text or call the school on your way if you can - they would far rather know you are coming.
Leaving early
Finished with forty minutes to spare? In most schools you will not be allowed to leave during the main exam sessions, and honestly, you shouldn't want to. Spare time is marks lying on the table: re-read the questions you rushed, check every "show that" actually shows it, re-do a calculation from scratch rather than just re-reading it (re-reading tends to nod through the original mistake), and make sure nothing on the back page went unseen. Examiners' reports say the same thing every year - checked papers score better. The exam ends when the invigilator says so; until then, the time is yours to use.
What invigilators can and can't help with
Invigilators are on your side for everything practical: a dead pen, more paper, an escort to the toilet, a wobbly desk, feeling unwell, or noting something that went wrong (which matters later if special consideration applies - if you feel ill during a paper, tell someone during or straight after, not weeks on). What they cannot do is anything about the content: they will not explain what a question means, confirm you have read it right, or hint at anything. If you think a paper itself has a misprint, raise your hand and say so - they can note it and report it. Content silence is not unfriendliness; it is the fairness everyone in the room is relying on.
If the fire alarm goes off
It happens somewhere every exam season, and there is a rehearsed procedure for it: you will be told to stop writing, leave everything on your desk, and file out under supervision, staying silent - the exam is paused, not abandoned. When you return, the lost time is added back and the paper resumes. You are not penalised for the interruption, and if it genuinely rattled your performance, that is exactly the sort of event special consideration exists for - your school reports it to the board. Your only jobs are: stop, stay quiet, follow instructions, and pick your pen back up when told.
