OICL AO common mistakes
OICL AO · Understand the traps and how to avoid them.
In Reasoning Ability puzzles and seating arrangements, the candidate starts drawing the arrangement before reading all clues, then has to erase and rebuild when a later condition (e.g., 'only two people sit between A and B' combined with a fixed end seat) contradicts the first draft.
Under a timed sectional clock, candidates skim the paragraph, latch onto the first two or three clues, and begin diagramming immediately; they treat the puzzle as a linear read rather than a constraint-satisfaction task, so they discover the contradiction only after investing minutes.
What to do instead
Spend the first 20-30 seconds classifying every clue as fixed (definite position/order) or conditional (either-or, 'not adjacent'). Start the diagram only from fixed clues, then apply conditional ones. If two clues force a branch, draw two small parallel cases rather than one and see which branch a later clue kills. Practise with a stopwatch so you learn to abandon a puzzle after 90 seconds without sunk-cost hesitation.
The candidate attempts every question in a Reasoning section in serial order, spending 3-4 minutes on one hard multi-constraint puzzle or a complex input-output set, and leaves 8-10 easy syllogism, inequality, or coding-decoding questions unattempted.
Serial-order answering feels fair and safe, and candidates fear that skipping a question means losing marks they cannot recover; they also misjudge how long a puzzle will take before starting it.
What to do instead
Do a 30-second scan of the section and answer standalone items (inequalities, syllogisms, blood relations, direction sense, alphanumeric series) first, banking 12-15 quick marks. Only then enter puzzle sets, and pick sets with fewer variables. Set a hard per-question cap of 60-75 seconds for standalone items and 4-5 minutes for a full puzzle set; move on when the cap hits.
In English Language, the candidate answers reading-comprehension questions from memory of the passage after one fast read, choosing options that repeat words from the passage rather than options that correctly paraphrase its meaning; they also skip the 'author's tone/inference' questions entirely.
Passage text is dense and time is short, so candidates pattern-match on lexical overlap; trap options are deliberately built to reuse passage vocabulary while inverting or overstating the claim, and inference questions feel riskier than factual ones.
What to do instead
Read the questions first, then read the passage once with those questions in mind. For each option, locate the exact line in the passage that supports or contradicts it and mark it; reject any option you cannot anchor to a line. Treat extreme words (always, never, only, all) as red flags. Practise 2-3 passages daily and log every trap type you fall for (word-match trap, scope shift, half-true).
On cloze tests, error-spotting, and sentence-improvement items, the candidate chooses the option that 'sounds right' without checking subject-verb agreement, preposition collocation, or parallel structure across the whole sentence.
Everyday spoken English tolerates errors that written exam English does not, and options are designed so that one distractor sounds natural to a casual reader. Candidates also read only the blank's neighbourhood, not the full sentence.
What to do instead
Apply a fixed checklist to every grammar item: subject-verb agreement, tense consistency, pronoun reference, preposition collocation, parallelism, and modifier placement. For cloze, read the entire sentence (and the sentence after) before choosing. Maintain an error log of collocations you got wrong (e.g., 'comprise of' vs 'comprise', 'superior to') and revise it weekly.
In Quantitative Aptitude, the candidate solves DI and arithmetic word problems by full manual calculation, writing out long division and multi-step percentages, instead of using approximation, ratio logic, or option elimination, and consequently finishes only 15-18 of the section's questions.
School habit rewards exact written computation, and candidates distrust approximation; they also do not memorise fraction-percentage tables, squares, and cubes, so every calculation starts from scratch.
What to do instead
Memorise the fraction-to-percentage table up to 1/20, squares to 30, cubes to 15, and common square roots. For DI, compute only the two or three values the question actually compares and use percentage-change shortcuts. Practise a 'no full division' rule: estimate first, then check which option bracket your estimate falls into. Time yourself at 45-50 seconds per DI question.
The candidate picks the topic order for arithmetic (time-work, pipes, boats, mixtures, partnership) by comfort rather than by exam weight, over-practising easy percentage and profit-loss sums while never drilling time-speed-distance, time-work, and mixture-allegation, which carry repeated marks in the mains-level paper.
Comfort topics give a quick accuracy boost and a false sense of progress; hard topics are avoided because early attempts are slow and demoralising, and candidates lack a structured method for them.
What to do instead
Build a topic-weight sheet from past papers, then allocate practice time inversely to your current accuracy on high-weight topics. For each weak topic, learn one standard method (e.g., LCM-based efficiency for time-work, allegation cross for mixtures) and solve 20 problems using only that method before mixing. Track accuracy per topic weekly and reallocate time to the lowest-accuracy high-weight topic.
For General Awareness, the candidate relies on month-old monthly current-affairs PDFs and generic static-GK lists, and cannot answer questions on recent RBI policy rates, insurance-sector regulators and schemes, or banking-appointment news from the last three to four months.
Static GK feels finite and reassuring, while current affairs feel endless; candidates also use stale compilations because they are easy to download, and they never revise, so what they read in month one is forgotten by exam day.
What to do instead
Maintain a rolling three-month current-affairs file, updated weekly, with separate sections for RBI/monetary policy, insurance (IRDAI, PMJJBY, PMSBY, APY, insurance FDI, new products), banking (mergers, capital infusion, new bank heads), and appointments/awards. Revise the file every Sunday and again in the last 10 days. Pair it with a compact static banking-and-insurance glossary (regulators, key Acts, headquarters, founding years) that you can recite cold.
In General Awareness, the candidate guesses on insurance-specific items (e.g., which policy covers which risk, what 'utmost good faith' or 'subrogation' means, IRDAI norms on agent commissions, or the difference between reinsurance and double insurance) because they prepared current affairs but treated the insurance portion as optional.
Insurance is a specialist subject and candidates from non-commerce backgrounds assume it is too technical, so they postpone it; the paper, however, reserves a meaningful share of awareness and professional-knowledge marks for exactly these concepts.
What to do instead
Study the seven principles of insurance (insurable interest, utmost good faith, indemnity, proximate cause, subrogation, contribution, mitigation) with one concrete example each. Learn the structure of the Insurance Act 1938, IRDA Act 1999, and LIC/GIC history, plus key IRDAI regulations (agent licensing, commission caps, solvency margin). Make one-page comparison tables: reinsurance vs double insurance, life vs general insurance, indemnity vs non-indemnity policies.
In Professional Knowledge (Insurance and Allied Subjects), the candidate memorises definitions but cannot apply them: they misidentify which principle governs a scenario, confuse 'insurance' with 'assurance', or fail numerical items on premium calculation, bonus types, surrender value, and claim settlement under policy conditions.
Definitions are easy to flashcard but scenario questions require mapping a fact pattern to a principle or product, and candidates never practise that mapping; numerical insurance topics are skipped because they seem peripheral to a 'knowledge' paper.
What to do instead
Convert every definition into a scenario drill: read a short fact pattern and name the principle, product, or clause involved. Build a product matrix (term, endowment, ULIP, money-back, whole life, annuity) with columns for death benefit, maturity benefit, bonus/surrender applicability, and tax treatment. Practise bonus (simple vs compound reversionary), surrender value, and premium computation numerically until you can do them without a formula sheet.
In Descriptive English, the candidate writes the essay and letter with no time plan, produces a long unstructured essay with no clear introduction-body-conclusion, exceeds or ignores the word limit, and leaves the letter unfinished or writes it in an informal register when a formal one is required.
The descriptive paper is typed or handwritten under a separate clock, and candidates spend most of it on the essay because it feels more important; they also never practise writing against a word count, so they misjudge length and pace.
What to do instead
Rehearse a fixed split: 10 minutes planning and outlining, 20-22 minutes for the essay (introduction stating the stand, 2-3 body paragraphs with one example or data point each, conclusion), and 12-15 minutes for the letter. Memorise the formal letter skeleton (sender address, date, receiver designation, subject line, salutation, body, complimentary close) and keep 3-4 insurance/banking examples ready for use. Practise at least two timed full papers and count words to calibrate.
