CFAT common mistakes
CFAT · Understand the traps and how to avoid them.
On analogy items, comparing the two stem words by topic or emotional tone (e.g., 'both are about the military') and then picking the option that feels similar in subject matter rather than matching the logical relationship.
Analogy stems often draw from concrete, familiar categories, so surface association fires faster than relational reasoning. The test-taker never states the bridge to themselves, so they cannot check whether the option's bridge is the same.
What to do instead
Force a one-sentence bridge before looking at options: 'A is a type of B', 'A is the tool used by B', 'A lacks B'. Then test each option by substituting it into that exact sentence. Eliminate any option whose bridge needs different wording, even if it is thematically close.
Treating word-meaning items as recall tests: choosing the answer that 'sounds like' a definition heard before, or rejecting a correct answer because the candidate has never used the word personally.
Vocabulary breadth varies widely and candidates over-weight personal familiarity. Rare but transparent words (Latin/Greek roots, prefixes) get skipped, and near-synonyms get collapsed into one meaning.
What to do instead
Decompose unknown words into prefix, root, and suffix and generate a provisional meaning before scanning options. When two options are near-synonyms, look for the one that differs in connotation, intensity, or part of speech; the distractors are usually built on a single misread syllable.
On reading-comprehension passages, selecting an answer that is true in real life or true somewhere in the passage, without checking that it answers the specific question asked (main idea vs. detail vs. inference vs. tone).
Passages are short and time pressure is high, so candidates read the question once, skim, and latch onto a familiar-sounding sentence. True-but-irrelevant options are deliberately included.
What to do instead
Classify the question type first and restate what it demands in three words ('main point', 'author's attitude', 'implied cause'). Reject any option that is accurate but does not match that demand, and verify the chosen line by pointing to the exact sentence that supports it.
Answering 'cannot be determined' too rarely on verbal logic items, instead assuming unstated facts (that a group described as larger must be stronger, or that a stated correlation implies causation).
Everyday reasoning fills gaps automatically, and candidates fear that 'cannot be determined' is a trick answer. Quantifier and conditional wording ('all', 'some', 'only if') is skimmed rather than parsed.
What to do instead
Rewrite each premise in symbolic shorthand and check whether the conclusion follows by the stated rule alone. If the conclusion needs one extra assumption, mark it 'cannot be determined'. Practise distinguishing 'some A are B' from 'all A are B', since that single word usually decides the item.
On spatial folding items (a flat net folded into a cube or box), tracking only two or three faces mentally and then guessing the rest, or forgetting that faces which look adjacent on the net may end up opposite each other.
Mental rotation degrades quickly beyond two transformations, and working memory drops the earlier orientation. Candidates also forget the rule that faces separated by exactly one face on a straight strip end up opposite.
What to do instead
Use the 'skip one' rule to fix opposite pairs first, then only rotate the remaining faces. Anchor one face as the front and write or say the position of each neighbour. If a question asks which cube is impossible, test the opposite-pair constraint before doing any rotation at all.
On rotated-figure and mirror-image items, choosing the option that looks most similar in overall shape while ignoring that it is a mirror image rather than a rotation, or vice versa.
Mirror and rotation look alike at small angles and under time pressure. Candidates compare silhouettes instead of tracking a distinctive asymmetric feature such as a notch, a dot, or a longer arm.
What to do instead
Pick one asymmetric landmark on the original and follow only that landmark through the transformation. For rotations, note whether it moves clockwise or counter-clockwise and by roughly how many degrees; for mirrors, check that the left-right order of two landmarks is reversed while their up-down order is unchanged.
On pattern-completion and hidden-figure items, searching for the whole target shape at once rather than for a distinctive sub-part, and giving up after a few seconds of scanning.
The embedded figure is usually rotated or partially overlapped by distractor lines, so whole-shape matching fails. Without a systematic scan the eye keeps returning to the same salient region.
What to do instead
Break the target into two or three line segments and hunt for the most unusual one first (an acute angle, a short parallel pair). Scan the field in a fixed order (left to right, top to bottom) rather than randomly, and accept that finding the figure typically takes 20 to 40 seconds.
On paper-folding-and-punching items, counting the number of holes correctly but placing them symmetrically when the fold was diagonal or off-centre, producing the right count in the wrong positions.
Candidates rehearse the fold sequence but not the reflection axis. A diagonal fold reflects across a slanted line, and the mental image defaults to vertical or horizontal symmetry.
What to do instead
Before unfolding, sketch the fold line and mark which side of it the punch sits. Unfold one fold at a time, reflecting the hole across that specific line, and only then move to the previous fold. Check the final pattern for the correct number of holes and the correct axis of symmetry.
On arithmetic and numerical-reasoning items, doing exact long computation by hand and running out of time, or estimating so loosely that the nearest answer options cannot be separated.
School habits favour exact calculation, but the answer choices are usually spaced widely enough for approximation. Conversely, rounding both operands aggressively can shift the result past a close distractor.
What to do instead
Round to two significant figures, compute, and check which option is within about 5 percent. Only do exact arithmetic when two options fall inside that band. For percentage and ratio items, convert to simple fractions (12.5 percent = one eighth) rather than multiplying decimals.
On word problems, grabbing the numbers and applying the operation that 'seems right' without writing the relationship, then answering the quantity asked for in the wrong units or answering an intermediate value.
Time pressure pushes candidates straight to computation, and the final sentence of the problem (which states what to solve for) is read before the setup is understood. Unit mismatches (minutes vs. hours, cents vs. dollars) go unnoticed.
What to do instead
Write one equation with named quantities before calculating, and underline the final question sentence. After computing, re-read that sentence and confirm the units and the quantity match; if the problem asks for a rate, verify the answer is a rate and not a total.
