NPSC Police Constable Exam common mistakes
NPSC Police Constable Exam · Understand the traps and how to avoid them.
Skipping the height, chest and weight measurement at home and discovering at the PST that the chest expansion is short by 1 cm or the height is borderline, with no time left to fix anything.
Candidates treat the PST as a formality and assume their everyday body measurements match the official ones. Measurement technique (barefoot, heels together, chin position, chest at full inspiration versus rest) shifts results by a centimetre or more, and Nagaland recruitment notifications specify exact minimums that many candidates never read carefully.
What to do instead
Get measured at a government hospital or a local gym with a stadiometer and tape, barefoot, heels together, and record height, chest at rest and chest at full expansion. Compare against the exact figures in the current NPSC/advertisement notification. If the chest expansion is marginal, start a daily breathing and posture routine (deep inspiration holds, swimming, push-ups) months before the test, not weeks.
Starting 1600 m or 5 km running practice only after the written result is declared, then failing the PET qualifying time or long jump and shot put distances.
The written exam consumes all available preparation time and the PET window is short. Running endurance and explosive power (long jump, shot put) adapt over eight to twelve weeks, so cramming produces injuries rather than speed. Candidates also practise on flat roads only and are surprised by the grass track and the technical rules of the long jump and shot put.
What to do instead
Begin a structured running plan at least three months before the written exam: three runs a week, one interval session, one tempo run, one long run, and add two sessions a week of long jump and shot put technique with a coach or experienced candidate. Time yourself over the exact distance monthly and record it against the qualifying standard. Practise the take-off board and the shot put throwing circle, not just raw strength.
Treating General English as a reading-only section and never drilling grammar rules, so error-spotting, fill-in-the-blanks and sentence-improvement questions are answered by ear.
School English in the region often emphasises literature and comprehension over formal grammar terminology. Candidates can read fluently but cannot identify a dangling modifier, a subject-verb agreement error with collective nouns, or the correct preposition after a verb.
What to do instead
Work through one grammar topic per week (subject-verb agreement, tenses, articles, prepositions, active-passive, direct-indirect speech) with 30 practice sentences each, and maintain an error log of every mistake with the rule that was violated. Revise the log weekly. Practise error-spotting on full sentences rather than single words.
Attempting every question in the Mathematics section in order, spending six or seven minutes on one long calculation and leaving easy later questions unanswered.
Candidates are trained to solve completely and show working, so they cannot abandon a question. Under timed conditions this instinct destroys the score because the paper rewards correct answers, not working, and negative marking punishes guesses.
What to do instead
Adopt a two-pass strategy in every mock: first pass answer only questions you can finish in under 60 seconds, second pass return to the rest. Practise approximation and elimination (check the last digit, estimate the magnitude, substitute options) and set a hard 90-second cap per question. Do ten full-length timed mocks before the exam and review which questions consumed disproportionate time.
Answering reasoning questions by intuition instead of drawing the diagram, so seating arrangement, blood relation and direction sense questions are answered wrongly under time pressure.
These questions look short and candidates believe they can hold the arrangement in their head. Working memory fails after three or four constraints, and the error is invisible because the reasoning feels correct.
What to do instead
Make the diagram compulsory: a row or circle sketch for seating, a tree for blood relations, a compass sketch for directions, and a table for syllogism. Practise 20 questions a day of one type until the diagram habit is automatic, then mix types. In mocks, count how many reasoning errors came from not drawing and track it to zero.
Preparing current affairs only from a monthly PDF read once, without linking events to states, schemes and appointments, so questions on Nagaland-specific and national developments are missed.
Current affairs is treated as passive reading. Candidates recognise a headline but cannot recall the associated state, ministry, scheme beneficiary or date, which is exactly what objective questions test.
What to do instead
Maintain a one-page weekly log with columns for event, place/state, person, scheme or organisation, and significance, and write entries by hand. Revise the last six months weekly and the last twelve months monthly. Include Nagaland state events, appointments and central schemes with special provisions for the North-East.
Ignoring Nagaland-specific general knowledge and relying only on national GK, so questions on state districts, tribes, festivals, rivers and administrative history are guessed.
National GK compendiums cover very little of Nagaland. Candidates assume state questions will be few, but a dedicated portion of the paper tests local knowledge, and it is the easiest section to score in because the syllabus is finite.
What to do instead
Build a one-page fact sheet per district covering headquarters, major tribes, festivals, rivers and notable features, plus a sheet on the major tribes and their festivals (for example Hornbill, Moatsu, Sekrenyi, Tuluni, Aoleang) and on state symbols, boundaries and statehood history. Revise these sheets weekly and test yourself with self-made flashcards.
Filling OMR bubbles carelessly, changing answers without fully erasing, or misaligning the serial number after skipping a question, so correct answers are machine-read as wrong.
Candidates practise on question papers and only encounter the OMR sheet on exam day. Under time pressure, one skipped question shifts every subsequent bubble, and faint erasures leave double marks.
What to do instead
Use an OMR sheet in every mock from the start. Develop a routine: answer, bubble immediately, and tick the question number in the booklet. Before starting a section, verify the bubble serial against the question serial. Use a good eraser and check that no dark smudge remains. Reserve the last five minutes to audit serial alignment.
Leaving physical preparation for the PET without any medical screening, then suffering a knee or ankle injury during long jump or shot put practice weeks before the test.
Candidates increase training load suddenly on hard surfaces, wear everyday shoes, and skip warm-up and strengthening. Long jump landing and shot put rotation load the joints heavily, and untreated minor pain becomes an injury that rules out the test.
What to do instead
Get a basic fitness and injury screening before starting, buy proper running and jumping shoes, and follow a warm-up and cool-down routine every session. Include strength work for calves, hamstrings, glutes and core twice a week. Progress weekly distance by no more than ten per cent and stop at sharp pain rather than pushing through it.
Misreading the notification on eligibility, age relaxation, category certificates and document format, so a candidate clears all stages but is rejected at document verification.
Candidates rely on what seniors or coaching centres say rather than the current advertisement. Rules on upper age limit, permanent residence or indigenous certificate, and the exact format and issuing authority of certificates change between notifications and are strictly enforced.
What to do instead
Download the current official notification and the corrigendum, and make a checklist of age as on the cut-off date, required educational certificate, category and local status certificates, and their exact formats. Get certificates issued months in advance and keep two attested photocopies plus originals in a single folder. Ask the designated office in writing if any requirement is unclear.
