Every semester, students lose five to fifteen marks to things that have nothing to do with knowledge — clock mismanagement, wrong question selection, booklet errors, and panic in the first ten minutes. These are the most repeated exam-day mistakes in Anna University halls, each with its boring, reliable fix.
Mistake 1: arriving with a logistics problem
Hall ticket not printed, ID forgotten, exam centre or hall number checked for the first time at 8:50 a.m. The fix is a kit packed the previous evening: hall ticket, college ID, two working pens plus a spare, pencil and scale for diagrams, permitted calculator, water, and the centre/hall/seat details confirmed. If anything about the hall ticket itself is wrong or missing, that has its own escalation path — raise it with your exam cell days before, not at the gate.
Mistake 2: writing before reading
The strongest habit in the hall: spend the first five minutes reading the entire paper and marking each question A (know it cold), B (can build it), C (shaky). Then sequence: open with one or two confident Part B answers to bank marks and settle nerves, sweep Part A, then work B-list questions, leaving C-list and the hardest choice for last. Students who start writing question 1 blind routinely discover at the end that their best questions got their worst remaining time.
Mistake 3: ignoring the choice structure
Where the paper offers either/or choices, the selection is the strategy — a minute comparing both options (can I draw its diagram? do I know its steps?) prevents the classic trap of starting the familiar-looking option and hitting a wall at step three. Pick the question whose middle you can see, not just its opening line.
Mistake 4: the runaway clock
The single biggest mark-loser: forty-five minutes on one beloved 13-marker while two questions die unattempted at the end. Budget roughly a minute and a half per mark — about twenty minutes for a 13-mark answer — and enforce it with checkpoints (“by 11:00 I must be on my third long answer”). An unattempted question earns a guaranteed zero; three slightly-rushed answers nearly always outscore two polished ones plus a blank. The answer-anatomy method makes twenty-minute answers feel spacious, because structure writes faster than prose.
Mistake 5: booklet and numbering errors
Wrong or missing question numbers, answers split across the booklet without cross-references, rough work scattered through fair pages, details on the cover filled in the last ninety seconds. The fixes are mechanical: number every answer boldly in the margin as you start it, begin each long answer on a fresh page, mark rough work as rough and strike it, and reserve the final ten minutes for the audit — question numbers against the paper, attempted-question tally, cover details, supplementary sheets tied and numbered.
Mistake 6: the blank-mind panic
Reading the paper and feeling nothing come back happens to prepared students — stress chemistry, not lost knowledge. The protocol: put the pen down, thirty seconds of slow breathing, then start the single easiest two-mark question on the paper. Retrieval unlocks retrieval; momentum returns within minutes. What feeds the panic is the doorway quiz-circle before the exam and the post-mortem immediately after — skip both, especially mid-series when the next paper’s 48-hour window has already started.
Mistake 7: surrendering a bad paper
A hard paper is hard for the whole hall, and results are effectively relative to it. The students who salvage grades from brutal papers are the ones who attempt everything — definitions, diagrams, first steps of methods — harvesting partial marks across the paper instead of polishing two answers and abandoning the rest. Walk out only when time ends, never when morale does. And if a paper does go badly: one subject is recoverable by design — see the arrear strategy and the CGPA recovery plan — but decide nothing on exam-day emotion.
