FFS Recruitment CBT common mistakes
FFS Recruitment CBT · Understand the traps and how to avoid them.
Selecting a verbal reasoning option because it contains a word or phrase copied from the passage, without checking whether the option preserves the passage's scope and qualifiers.
Under time pressure, candidates fall back on keyword spotting and stop reading once a familiar term appears, so they miss words such as all, only, some, except, and not.
What to do instead
For every passage question, restate the claim in your own words before looking at the options; reject any option that changes a qualifier or widens/narrows the scope. Practise 10 paraphrase-matching items daily and write down the exact word that makes each wrong option wrong.
Starting exact arithmetic immediately in a quantitative problem and then picking an answer that is off by a factor of 10, 100, or a unit conversion.
Candidates treat calculation speed as the goal and skip the 10-second estimate that would reveal an impossible magnitude or unit mismatch.
What to do instead
Before calculating, write a rough estimate and the expected unit; after calculating, compare the result with the estimate and check the unit before selecting an option. Drill 15 mixed unit-conversion items with a mandatory estimate line.
Skipping algebra word problems after reading them twice, then guessing, because no equation is written down.
Candidates try to hold the whole relationship in their head instead of translating each sentence into a mathematical statement, so the problem feels harder than it is.
What to do instead
Use a fixed translation routine: define the unknown (let x = ...), convert each clause into an equation or inequality, and only then solve. Practise 20 two-clause and three-clause word problems where the mark is awarded for the correct equation setup, not the final number.
Answering current-affairs questions from memory of old preparation material, such as naming a former office-holder or quoting a superseded scheme, without checking the date of the fact.
Candidates reuse notes and apps that were not updated, and they do not track the recency of each fact they have memorised.
What to do instead
Maintain a dated current-affairs log with a strict six-month cutoff; for every entry record the source and date. Before the exam, verify office-holders, scheme names, and major appointments against official government or institution websites rather than social-media summaries.
Choosing water as the extinguishing agent for an electrical, cooking-oil, or flammable-liquid fire because water is associated with 'putting out fires' in general.
Candidates memorise fire classes and extinguisher names as separate lists rather than as a decision rule linking fuel type to safe agent and method.
What to do instead
Build a fuel-to-agent matrix covering ordinary combustibles, flammable liquids, electrical equipment, cooking oils, and gases. For each scenario, state the class, the safe agent, and the unsafe agent with the reason. Practise scenario stems rather than isolated definitions.
Answering science items from everyday intuition, for example assuming heavier objects always fall faster or that a metal object is always colder than wood at the same room temperature.
Everyday experience produces plausible but incorrect mental models, and candidates do not test those models against the underlying principle.
What to do instead
Study each concept with one counterexample and one explanation of why the intuitive answer is wrong. Use concept-first flashcards that require explaining the principle, not just naming the correct option.
Confusing RAM with permanent storage, or 'Save' with 'Save As', and misidentifying basic shortcuts when asked what a command does.
Candidates memorise shortcut lists and menu names without a model of what the computer is actually doing, so similar-sounding functions blur together.
What to do instead
Perform the operations hands-on: create a file, edit it, use Save and Save As, and observe where the file is stored. Draw a simple diagram separating processor, memory, and storage, and pair each shortcut with the action it performs.
In abstract reasoning, choosing the next figure after identifying a pattern in only the first two given figures, without checking that the rule holds for every figure in the series.
The brain prefers the first plausible pattern, and candidates stop testing once they find one, missing a second rule such as alternating rotation direction or a changing element count.
What to do instead
State the candidate rule in words, then verify it against every given figure before looking at the options. If any figure breaks the rule, discard it and search for a second dimension. Use elimination on options as a cross-check.
Answering public-service ethics questions by personal kindness or loyalty, for example choosing to speed up a relative's file or to conceal a colleague's minor breach.
Candidates apply everyday personal morality instead of the role-based standards of impartiality, confidentiality, transparency, and conflict-of-interest avoidance.
What to do instead
Apply a fixed four-question test to each dilemma: Is it lawful? Is it consistent with policy? Is it impartial and free of personal interest? Would I be comfortable if it were public? Practise writing the justification, not just selecting the option.
Spending too long on one reading passage or one calculation and leaving later questions blank because the section timer expires.
Candidates have no per-section pacing benchmark and treat every question as equally worth completing, so early questions consume the time needed for easy later marks.
What to do instead
Set section time budgets in advance and rehearse them in full-length mocks: for example, a hard stop of 90 seconds per verbal item. Flag and guess any item that exceeds the limit, then return only if time remains.
