JEMAT common mistakes
JEMAT · Understand the traps and how to avoid them.
In Quantitative Aptitude, spending a fixed block of time on each question in sequence, so a single hard arithmetic problem early on consumes the minutes that easy percentage and ratio questions later would have earned quickly.
School habits condition candidates to finish every question in order, and mock tests are rarely practised with a strict per-question cut-off, so the sunk-cost feeling of 'I've almost got it' overrides the strategic value of skipping. JEMAT is speed-scored, and the arithmetic section rewards coverage of easy items over conquest of hard ones.
What to do instead
Adopt a two-pass routine: first pass, answer only questions solvable in under 60 seconds and mark the rest; second pass, return to marked items with whatever time remains. In practice, time yourself with a visible clock and force a skip at 75 seconds on any single question. Track how many 'abandoned then solved on second pass' questions you get right to prove the strategy works.
In Quantitative Aptitude, computing full exact values for percentage-change, profit-loss, and simple/compound interest problems instead of using base-100 assumptions and approximation, producing long multiplication errors under time pressure.
Candidates default to the formula-and-calculate method taught in school because it feels rigorous, but exam options are usually spaced widely enough that estimation suffices. Manual multi-step arithmetic under a clock is where sign errors and misplaced decimals creep in.
What to do instead
Drill the base-100 and fraction-equivalence shortcuts (12.5% = 1/8, 16.66% = 1/6, successive changes via multiplying factors). For each practice set, solve half the questions by exact calculation and half by approximation, then compare accuracy and time. Build a one-page sheet of the fraction-percentage table and memorise it before the exam.
In Reasoning and General Intelligence, starting a seating-arrangement or blood-relation puzzle by drawing the diagram directly from the first clue instead of scanning all clues to identify the fixed anchor, then restarting the diagram two or three times when a contradiction appears.
Puzzle clues are deliberately ordered so the first one is rarely the most constraining; candidates read linearly and commit to a layout before they know which clue pins a position absolutely. Restarting diagrams silently burns three to four minutes per puzzle.
What to do instead
Before drawing anything, read all clues and label each as definite (fixes a position), relative (links two people), or negative (excludes a position). Start the diagram from the definite clue, then apply relative clues. Practise 20 puzzles with a rule of no redrawing: if a contradiction appears, the error is in your reading of a clue, so re-read rather than restart.
In Reasoning and General Intelligence, treating syllogism and logical-deduction questions by intuition about real-world truth rather than by formal set relationships, so conclusions that are factually plausible but not logically entailed are marked as following.
Everyday reasoning rewards plausibility, and the wording of syllogism items often uses familiar categories where real-world knowledge conflicts with the formal 'some/all/no' rules. Candidates who have not practised Venn-diagram method answer from belief rather than structure.
What to do instead
Force the Venn-diagram method for every syllogism item: draw the minimum-necessary diagram from the premises, then test whether the conclusion holds in every possible diagram. Memorise the standard possibility rules (e.g., 'some A are B' does not imply 'some A are not B'). Do 30 items where the conclusion is false in reality but valid in form, and note how often intuition misleads you.
In English Language and Comprehension, reading the passage first in full before looking at the questions, then re-reading the passage for each question because the details were not retained.
School comprehension habits favour a full careful read, but exam passages are long and questions are usually detail- or inference-specific. Without a purpose, the first read is passive and nothing is anchored, so every question triggers a fresh scan.
What to do instead
Skim the questions first to identify the keyword each one targets, then read the passage once with those keywords in mind, underlining the sentence that answers each. Answer vocabulary and direct-detail questions first, inference and tone questions last. Time a full passage set and aim to cut total reading time by a third without losing accuracy.
In English Language and Comprehension, choosing a vocabulary or synonym answer based on the word's most common meaning without checking the sentence context, and choosing an inference option that is true in general but not supported by the passage.
Word lists are studied in isolation, so candidates recall a single dominant sense of a word. Inference options are written to be plausible and morally agreeable, which makes them feel safe even when the passage never states them.
What to do instead
For vocabulary in context, substitute each option back into the sentence and check grammatical and semantic fit before choosing. For inference, require an explicit textual hook: if you cannot point to the sentence that licenses the option, reject it. Practise with a highlighter rule: no highlight, no answer.
In General Awareness / Business and Management Aptitude, answering business and management questions from general impressions of well-known companies and brands rather than from defined concepts such as economies of scale, break-even, span of control, or the marketing mix.
The section name invites candidates to rely on current-affairs reading and business news, but many items test textbook management and economics concepts. Familiarity with a company's reputation creates false confidence and pulls attention away from the concept being tested.
What to do instead
Build a concept glossary of roughly 100 core terms across management functions, marketing, finance basics, and business economics, each with a one-line definition and one example. For every practice question you miss, write the underlying concept rather than the fact. Revise the glossary weekly so definitions, not impressions, drive the answer.
In General Awareness / Business and Management Aptitude, spending disproportionate preparation time on static general knowledge and current affairs while neglecting the business-economics and management-theory portion that carries a large share of the section.
Current affairs feels urgent and is easy to consume passively through news and social media, whereas management theory requires structured study. Candidates therefore over-invest in the comfortable activity and under-invest in the higher-yield one.
What to do instead
Map the syllabus explicitly and allocate study hours by expected question share, not by comfort. Keep a weekly log of hours per topic and rebalance if business and management topics fall below their target share. Use current-affairs time as a short daily supplement, not the main preparation.
Across all four sections, taking full-length mocks without reproducing exam conditions (pauses, phone, notes open, no fixed sectional timing), so practice scores overstate readiness and the candidate never rehearses the transition between sections.
Untimed practice is more comfortable and gives a pleasant score, and candidates use mocks to learn content rather than to rehearse the exam. The result is that pacing, stamina, and sectional switching are untested until the real exam.
What to do instead
Schedule at least four full-length mocks under strict conditions: single sitting, no notes, no phone, one continuous timer, and a fixed sectional time budget decided in advance. Review each mock within 24 hours, separating errors into knowledge gaps, careless slips, and pacing failures, and change one behaviour per mock.
In the final two weeks, attempting new and harder topics instead of consolidating error logs, so previously made mistakes repeat and confidence erodes on the eve of the exam.
Anxiety drives candidates toward novelty because new material feels like progress, and revising old errors feels like admitting weakness. But repeated errors in familiar topics cost more marks than unfamiliar hard topics would gain.
What to do instead
Maintain an error log from the first mock onward, recording the question, the wrong reasoning, and the correct method. In the last fortnight, work only from the log and a short formula and concept sheet, re-solving each logged question cold. Retire an entry only after solving it correctly twice without notes.
