NTN FrontLine Police common mistakes

NTN FrontLine Police · Understand the traps and how to avoid them.

Mistake 1

On video scenarios, picking the option that feels most morally satisfying (confronting the rude citizen, defending the officer) instead of the option that follows procedure and keeps the situation safe.

Candidates treat the video section as a personality or ethics test and answer as a private citizen would, forgetting that every option is a policy-constrained workplace choice.

What to do instead

Before choosing, run a fixed filter: (1) anyone unsafe? (2) does the option follow policy and chain of command? (3) does it de-escalate? Eliminate any option that skips a required notification or escalates verbally, then rank the survivors.

Mistake 2

Choosing the accommodating answer to a hostile or upset citizen (apologising, promising an outcome, agreeing the officer was wrong) rather than the answer that acknowledges the feeling and then sets a clear limit.

Candidates confuse empathy with agreement, and 'de-escalation' with giving the person what they want.

What to do instead

Memorise the three-part pattern and test each option against it: name the emotion, state the limit or rule, offer a legitimate choice. Options that promise something outside the officer's authority are wrong.

Mistake 3

Reading the question stem after watching the video and answering the general question 'how did the officer do?' when the stem actually asks for the NEXT action, the FIRST action, or the LEAST appropriate response.

Time pressure and the story-like video pull attention to the plot; candidates answer out of memory of the scenario rather than the wording of the stem.

What to do instead

Read the stem before the video plays when possible, and re-read it after. Circle the operative words (next, first, most, least) and require the chosen option to satisfy that exact word.

Mistake 4

Selecting an answer because the topic was covered in the passage, even though the passage never states that specific claim.

Passages look familiar (policy memos, procedural notices), so candidates fill gaps with what they already believe about policing or workplaces.

What to do instead

For every option you are tempted by, put a finger on the line in the passage that proves it. If you cannot locate the line, the option is wrong no matter how true it is in real life.

Mistake 5

Missing scope words: choosing an answer that says 'all', 'always', or 'must' when the passage says 'some', 'generally', or 'may' - or the reverse.

Answer choices are paraphrases, and the paraphrase feels close enough; the qualifier is the one word that changes the truth value.

What to do instead

Before comparing options, underline the quantifier in the passage and in each option. Match them one to one; treat any mismatch in qualifier strength as an automatic elimination.

Mistake 6

Choosing the answer that sounds right when read silently, producing comma splices, run-ons, and fragments in the sentence-correction items.

Spoken rhythm hides punctuation errors; a comma where a speaker would pause feels correct even when it joins two independent clauses.

What to do instead

Count the independent clauses in each option and check the joining device: period, semicolon, or comma plus a coordinating conjunction. Any option joining two full clauses with only a comma is out.

Mistake 7

Matching the verb to the nearest noun instead of the real subject when a phrase sits between them ('The officer, along with the two witnesses, ___'), and letting a pronoun point to the wrong noun.

Proximity attraction: the ear locks onto the last noun it heard, and long sentences bury the actual subject.

What to do instead

Cross out everything between the subject and the verb with your pencil, then read the core sentence. For pronouns, name the noun the pronoun replaces out loud and confirm it is the intended one and agrees in number.

Mistake 8

Stopping after the first calculation - finding the discount, the unit rate, or the average - and selecting that number as the answer when the question asked for the final price, the total, or the change.

The problem has several steps and the first result is a plausible-looking number sitting right there among the answer choices.

What to do instead

Before computing, write the last line of the problem as a question with a label ('final price = ?', 'change = ?'). Do not look at the answer choices until that labelled value is produced.

Mistake 9

Making place-value and decimal-alignment errors when working money, averages, and percent problems by hand, and accepting a total that is wildly off in magnitude.

Candidates rely on mental shortcuts under a timer and never check whether the result is in the right ballpark.

What to do instead

Set the work up vertically with decimal points aligned, and spend five seconds on a rough estimate (round to whole numbers) before choosing. If the answer is an order of magnitude away from the estimate, redo the setup.

Mistake 10

Choosing an inference answer that goes one step beyond the passage - drawing a conclusion about motive, cause, or future action that the text supports only loosely.

Inference items feel like they reward clever reading, so candidates pick the most insightful-sounding option rather than the most defensible one.

What to do instead

Apply the 'must be true' test: the correct inference is the one the passage makes unavoidable. If a reasonable person could accept the passage and still deny the option, eliminate it.
