Verbal Reasoning

  • 'True' means the statement follows only from the passage; 'False' means the passage contradicts it; 'Cannot say' means the passage neither confirms nor denies it, even if real-world knowledge suggests an answer.

  • A statement that merely restates a passage fact in different words is True; a statement that adds one unsupported detail (a cause, a number, a comparison) becomes Cannot say.

  • Watch quantifier swaps: 'all' to 'some', 'most' to 'all', and 'may' to 'will' each change a supported claim into an unsupported one.

  • Watch scope words: 'only', 'never', 'always', 'at least', 'unless' and 'except' invert or narrow meaning and are frequent sources of error.

  • Cause and effect are separate claims: a passage stating two events occurred together does not support a statement that one caused the other.

  • For 'select the statement that follows', test each option against the passage alone; eliminate options needing outside knowledge before comparing the remainder.

  • For main-idea items, the correct option must cover the whole passage; an option true of one sentence only is a detail, not the main idea.

  • For vocabulary-in-context, substitute each option back into the sentence and keep only the one preserving the original meaning and tone.

Numerical Reasoning

  • Percentage change = (new − old) ÷ old × 100; a rise from 80 to 100 is +25%, while a fall from 100 to 80 is −20%.

  • To increase by p%, multiply by (1 + p/100); to decrease by p%, multiply by (1 − p/100). Successive changes multiply: +10% then −10% gives ×0.99, a net −1%.

  • Reverse percentages: if a price after a 20% rise is 96, the original is 96 ÷ 1.20 = 80, not 96 − 20%.

  • Ratio sharing: total ÷ sum of ratio parts gives one part; multiply by each ratio number. Three-way split 2:3:5 of 200 gives 40, 60, 100.

  • Average = total ÷ count; the combined average of two groups weights each group mean by its count, not by simple averaging of the two means.

  • Rates: distance = speed × time; time = distance ÷ speed. For work, combined rate = sum of individual rates, so time together = 1 ÷ (1/a + 1/b).

  • Unit conversion in chains: convert to a common unit first, then compute; 1 hour = 60 minutes, 1 km = 1000 m, 1 tonne = 1000 kg.

  • Percentage points versus percent: a rate moving from 20% to 25% rises 5 percentage points but 25% in relative terms.

  • Estimate before computing: round to two significant figures to identify the correct option, then verify exactly only if two options remain close.

Logical / Abstract Reasoning

  • In number sequences, check differences first, then ratios, then alternating or two interleaved sequences (odd positions and even positions follow separate rules).

  • Common sequence rules: add increasing amounts (+2, +3, +4), multiply by a constant, square/cube numbers, Fibonacci-style (each term is the sum of the previous two).

  • Letter series: convert letters to positions (A=1 … Z=26); a constant gap of 3 means +3 per step, and reversal means the alphabet runs backwards.

  • In syllogisms, 'All A are B' and 'All B are C' gives 'All A are C'; 'Some A are B' cannot be reversed into 'Some B are A' unless existence is stated.

  • 'No A are B' plus 'All C are A' gives 'No C are B'; a valid conclusion must hold in every arrangement satisfying the premises.

  • In seating or ordering puzzles, draw positions as slots and place the most constrained item first; fixed constraints (ends, adjacency) eliminate options fastest.

  • Odd-one-out items: test each option against a single rule (number of sides, symmetry, closed regions, rotation); the correct answer breaks exactly one consistent rule.

  • For matrix or series figures, track rotation (clockwise/counter-clockwise and degrees), shading alternation, and element count separately, since one feature often changes while another stays fixed.

Situational Judgement and Interpersonal Skills

  • Rank responses by the order: safety of people first, then legal and policy compliance, then honest communication, then task efficiency, then personal convenience.

  • Escalate when the issue exceeds your authority, involves a safety hazard, or is illegal; handle directly when it is within your role and a conversation can resolve it.

  • Communicate concerns to the person directly and privately before involving a manager, unless the conduct is unsafe, unlawful, or already reported and unresolved.

  • In 'most/least effective' items, judge each option against the stated role and policy; an effective answer respects both the chain of command and the duty to report.

  • When a colleague errs, address the behaviour and its impact, not the person's character; offer a specific corrective action.

  • Acknowledging a mistake promptly and stating the fix outranks concealing it or shifting blame, because concealment compounds the original error.

  • Customer or public-facing scenarios: confirm the facts, explain what you can do within policy, and state the next step and timeframe rather than only apologising.

  • Team conflict: separate the people from the problem, restate each side's interest, and propose an option that meets the shared operational goal.

Mechanical Comprehension and Spatial Awareness

  • Lever: effort × effort arm = load × load arm; a longer effort arm reduces the effort needed. Three classes differ by the order of fulcrum, load and effort.

  • Mechanical advantage of a pulley system equals the number of rope sections supporting the movable load; a single fixed pulley changes direction only, giving MA = 1.

  • Gear trains: meshed gears turn in opposite directions, and the speed ratio is the inverse of the tooth ratio; a small gear driving a large gear slows the output and increases torque.

  • Hydraulics follow Pascal's principle: pressure is equal throughout, so force ÷ area is constant and a larger piston gives greater force over a shorter stroke.

  • Work = force × distance moved in the direction of the force; power = work ÷ time. Holding a load stationary does no work in the physics sense.

  • Electrical basics: V = I × R; in a series circuit current is the same throughout and resistances add; in parallel circuits voltage is equal across branches.

  • Density comparison decides flotation: an object floats if its density is less than the fluid's, and sinks if greater; shape affects displacement, not density.

  • Spatial folding: count faces, edges and vertices of the net (a cube net has 6 squares, 12 edges); opposite faces on a net never share an edge.

  • Rotation and reflection: a 90° turn changes orientation but not shape or size; a reflection reverses handedness, which a rotation never does.
