DSSSB PRT common mistakes
DSSSB PRT · Understand the traps and how to avoid them.
Spending equal time on every General Awareness question, including ones on obscure state schemes or sports records, instead of answering the ones you know and moving on within 15–20 seconds.
General Awareness in DSSSB PRT is broad and shallow; candidates treat it like a knowledge test where every item is worth fighting for, so they burn time that the arithmetic section needs. The 100-question, 100-mark paper with negative marking rewards pace over perfection.
What to do instead
Adopt a two-pass rule: in pass one answer only items you resolve in under 20 seconds; mark the rest and return only if time remains. Before the exam, build a one-page revision sheet of high-frequency areas (Indian Constitution articles, national symbols, basic science, current schemes, books and authors) so recall is instant rather than reconstructive.
Guessing on General Awareness items with negative marking because 'it might be right', rather than leaving genuinely unknown items blank.
Candidates carry over a habit from papers without negative marking and feel that a blank is a wasted opportunity. Under 0.25 negative marking, a blind four-option guess has negative expected value unless at least one option can be eliminated.
What to do instead
Set an explicit personal rule before entering the hall: attempt only if you can eliminate at least one option or have a genuine partial memory; otherwise leave blank. Practise this in mock tests and count how many blind guesses you made, so the discipline is trained rather than decided under pressure.
Treating reasoning questions as puzzles to be solved from scratch, spending three or four minutes on one seating-arrangement or blood-relation item instead of applying a standard diagram.
Reasoning sections reward method recognition, but candidates who have not drilled category-wise patterns default to trial and error. Under time pressure, trial and error on a five-person seating arrangement easily consumes five minutes for one mark.
What to do instead
Learn one fixed notation per topic (linear arrangement rows, circular with fixed facing, family-tree symbols for blood relations, Venn circles for syllogism) and drill 20 items per topic until the diagram is automatic. In the exam, if a puzzle is not resolved in 90 seconds, mark it and move on; return only after the arithmetic section is complete.
Solving syllogism questions by intuition about real-world truth instead of applying the Venn-diagram method to the stated premises.
Candidates read 'All pens are books' and let everyday knowledge about pens interfere. DSSSB-style syllogisms test formal validity, so a conclusion that is factually sensible but not entailed by the premises is still wrong.
What to do instead
For every syllogism, draw the minimum-overlap Venn diagram for the premises, then test whether the conclusion holds in every possible diagram. Reject any conclusion that fails in even one valid configuration. Practise the possibility-versus-certainty distinction separately, since 'can be concluded' and 'follows definitely' are different asks.
Doing arithmetic questions in strict serial order, so a single long division or percentage problem early in the section stalls the rest of the paper.
Candidates equate completing the section with answering in order, and the arithmetic section mixes 30-second items with two-minute ones. Getting stuck on one calculation costs several easy marks later.
What to do instead
Sweep the arithmetic section twice: first collect all one-step items (unitary method, average, simple interest, simplification), then return to multi-step ones. Keep rough work numbered and in a single column so you can resume a half-solved problem without re-reading it.
Computing percentages, ratios and averages with full long multiplication instead of using fraction equivalents and approximation.
School habits persist; candidates never build a mental table of common fraction-percentage pairs, so 12.5% of 640 becomes a written calculation. This doubles or triples time per item in a section where speed is the real difficulty.
What to do instead
Memorise the standard conversions (1/8 = 12.5%, 1/6 = 16.66%, 1/16 = 6.25%, 3/8 = 37.5%) and the squares up to 30 and cubes up to 15. In options-based questions, estimate first: if options are far apart, approximation alone identifies the answer and you skip exact computation.
Reading Hindi passages once at full speed and then answering comprehension questions from memory without returning to the passage text.
Candidates assume comprehension questions are general-knowledge items and trust recall. In Hindi passages, options often hinge on a single word or on the difference between the literal meaning and the intended (लाक्षणिक) meaning, which memory blurs.
What to do instead
For each question, locate and re-read the specific sentence or paragraph that decides it before choosing. Flag vocabulary questions (पर्यायवाची, विलोम, मुहावरा) and answer them from your own word list rather than the passage, since these are recall items, not comprehension items.
Confusing near-synonym Hindi grammar terms and applying the wrong label, for example mixing संधि with समास or अलंकार with रस when the question names the category.
Hindi grammar terminology is taught in clusters and candidates learn definitions without practising identification on words. Under exam pressure, the category name in the stem is skipped and the option is chosen by vague familiarity.
What to do instead
Build a classification drill: take 50 words and label each as संधि (with type: स्वर/व्यंजन/विसर्ग), समास (with type), उपसर्ग, or प्रत्यय. Do the same for अलंकार versus रस with one example each. Read the stem first and note which category is being asked before looking at the options.
Answering English grammar questions by what 'sounds right' rather than identifying the tested rule, leading to errors on subject-verb agreement with intervening phrases, articles, and prepositions.
Everyday spoken English tolerates constructions that formal written English rejects, and candidates have not isolated the specific rules DSSSB tests. Items like 'One of the boys ___' or 'Neither of the answers ___' are decided by rule, not by ear.
What to do instead
Maintain a rule sheet of the ten most-tested structures (one of + plural noun + singular verb; neither/either + singular; collective nouns; articles before unique objects; fixed prepositions such as 'comprise of' being wrong). For each practice item, write the rule name beside the answer; if you cannot name the rule, treat the item as unresolved.
Using the same slow reading speed for English comprehension and para-jumbles as for a grammar item, leaving the last questions unattempted.
Candidates treat all English items as equally time-costly, but a comprehension set of five questions is answered faster by skimming the questions first and then scanning the passage, while a grammar fill-in takes seconds if the rule is known.
What to do instead
Sequence the English section by cost: do grammar and vocabulary items first, then para-jumbles (look for opening-sentence and pronoun-link cues), then comprehension. For comprehension, read the questions before the passage and scan for the relevant lines instead of reading every sentence at equal depth.
