ACET (Philippines University Entrance Tests) common mistakes

ACET · Understand the traps and how to avoid them.

Mistake 1

Reading the passage once at normal speed and then answering comprehension questions from memory, without returning to the text to verify each option.

Under time pressure candidates treat the passage as a story to understand rather than a source to be mined, so they answer from gist impressions and get seduced by options that are true in general but not stated in the passage.

What to do instead

For every comprehension question, locate and underline the exact line(s) that decide the answer before choosing an option; reject any option you cannot tie to a specific sentence.

Mistake 2

Choosing a vocabulary or analogy answer on the basis of how the word 'sounds' or a loose association, without stating the precise relationship in a sentence.

Candidates often know a vague sense of a word but not its exact meaning or its part of speech, and exam distractors are built from those near-misses and wrong-sense associations.

What to do instead

Before selecting, write the relationship as a short sentence (e.g. 'A scalpel is a tool used by a surgeon') and check the option pair fits the same sentence; for single words, substitute the option into an original sentence and test the meaning.

Mistake 3

Leaving grammar and usage items unanswered or choosing by ear when the sentence contains a long intervening phrase between subject and verb, or an inverted construction.

Proximity attraction and unusual word order override the candidate's internal grammar rules; the ear latches onto the nearest noun rather than the true subject.

What to do instead

Bracket or cross out prepositional phrases and relative clauses, then read subject and verb together; for inverted or question-form sentences, rewrite them in plain subject-verb-object order before judging agreement.

Mistake 4

Spending a disproportionate block of time on one hard calculation or multi-step word problem, leaving later easy items unattempted.

Candidates treat every question as equally mandatory and fear that skipping looks like giving up, so they sink time into a single item without tracking elapsed time.

What to do instead

Adopt a two-pass strategy: on the first pass answer only items solvable within about a minute, mark the rest, and return with remaining time; practise with a visible timer to build the habit of abandoning an item after a set threshold.

Mistake 5

Setting up word problems with the wrong operation or an unlabelled equation, then computing correctly but answering the wrong quantity.

Candidates translate keywords ('more than', 'times as many') directly into operations without defining what each variable represents, and they do not check what the question actually asks for.

What to do instead

Write a 'Let x = ...' definition line for each unknown, translate the problem sentence by sentence into an equation, and finish by circling the requested quantity and checking it against the units and rough magnitude.

Mistake 6

Making sign, fraction, and order-of-operations slips in multi-step simplification, especially with negative numbers and nested brackets.

Working memory is loaded by the structure of the expression, so the arithmetic is rushed and a dropped minus or inverted fraction goes unnoticed; there is no intermediate check.

What to do instead

Work one operation per line, keep brackets until the inner expression is fully simplified, and substitute the final answer back into the original expression (or test with a simple number) to verify.

Mistake 7

Answering science items from everyday intuition or a half-remembered fact instead of the underlying principle, e.g. assuming heavier objects fall faster or that heat and temperature are the same.

Everyday experience and imprecise language generate plausible but wrong mental models, and candidates do not distinguish a definition from a common misconception.

What to do instead

For each topic, keep a one-line statement of the governing principle and a named counterexample to the common misconception; before answering, identify which principle the item is testing and check the option against it.

Mistake 8

Ignoring units and quantities when reading data, diagrams, or experimental descriptions, e.g. mixing grams and kilograms or reading a graph axis at the wrong scale.

Candidates focus on the numbers and skip the labels, and graph axes with non-unit increments or broken scales are easy to misread at speed.

What to do instead

Read every axis label and unit before extracting a value, convert all quantities to one unit at the start, and sanity-check the answer's order of magnitude against the described situation.

Mistake 9

Choosing an abstract-reasoning option that matches the overall 'look' of the sequence rather than verifying the specific rule that generates each element.

Pattern items are designed with attractive near-miss distractors that share most features; candidates pattern-match holistically and stop at the first plausible rule.

What to do instead

Isolate one attribute at a time (number of sides, rotation, shading, position, count) and state the rule for each; only accept an option that satisfies all stated rules simultaneously, and test the rule backwards on the given figures.

Mistake 10

Rushing the final items in a section or misaligning answers on the answer sheet after skipping a question.

Fatigue and time pressure at the end of a section, combined with skipping items and then filling answers without re-checking the numbering, cause whole runs of answers to shift by one.

What to do instead

Fill answers as you go rather than in batches, mark skipped items clearly in the booklet, and reserve the last minute of each section to verify that the answer-sheet numbering aligns with the question numbers.
