Free JCF Entrance Exam Exam Flashcards

Work brackets first, then powers/roots, then multiplication and division left to right, then addition and subtraction left to right. Multiplication and division are equal rank, so do them in the order they appear, not multiplication always before division.

Find the greatest common factor (GCF) of the numerator and denominator and divide both by it. For 18/24, the GCF is 6, so 18÷6=3 and 24÷6=4, giving 3/4.

Convert the percent to a decimal by dividing by 100, then multiply: 25% = 0.25, and 0.25 × 320 = 80. For simple percentages like 25% or 50%, it is often quicker to use the matching fraction (a quarter or a half).

Convert both fractions to an equivalent form with a common denominator (often the lowest common multiple of the two denominators), then add or subtract only the numerators, keeping the denominator the same.

Speed = Distance ÷ Time. Rearrange it depending on what is missing: Distance = Speed × Time, or Time = Distance ÷ Speed.

Divide the total amount by the number of people to get each share. Check the answer by multiplying the share back by the group size; it should equal the original total.

Add the ratio numbers to find the total number of parts (2+3=5), divide the total amount by that number of parts to find the value of one part, then multiply that value by each ratio number.

Area = length × width. The common mistake is mixing units (for example, one measurement in feet and another in inches) — always convert both measurements to the same unit before multiplying.

Write 'i' before 'e' except after 'c' (believe, receive). Some common words break the rule anyway, such as 'weird' and 'science', so treat it as a helpful guide rather than an absolute law.

It is easy to drop one of its doubled letters. Remember it has two c's and two m's ('two Cs, two Ms') to avoid writing only one of either.

The word contains 'finite,' not 'finate.' Spelling it the way it sounds causes the common error, so anchor the spelling to the root word 'finite' instead of pronunciation.

Double the final consonant when a word ends in a single vowel followed by a single consonant on a stressed syllable. Do not double it after a long vowel sound or when the final syllable is unstressed (e.g., 'visit' → 'visited', not 'visitted').

'Government' keeps a silent 'n' before '-ment', and 'knowledge' keeps a silent 'd' before the final '-ge'. Say the word slowly in your head, part by part, to catch these dropped letters.

A singular subject takes a singular verb, and a plural subject takes a plural verb. Words such as 'each,' 'every,' and 'neither' are treated as singular, even when they refer to a group.

'Affect' is usually a verb meaning to influence something ('The heat affected his performance'). 'Effect' is usually a noun meaning the result of something ('The effect was fatigue').

'There' shows place or existence ('over there'), 'their' shows possession ('their vehicle'), and 'they're' is a contraction of 'they are.'

The verb agrees with the subject closest to it, not the first one listed. For example, 'Neither the officers nor the sergeant was late' — the verb matches 'sergeant,' the nearer subject.

Use 'who' if you could replace it with 'he' or 'she' (a subject), and use 'whom' if you could replace it with 'him' or 'her' (an object).

Place a comma before the quotation, capitalize the first word inside the quotation marks, and put the closing punctuation mark inside the quotation marks.

The main idea is the overall point that the entire passage supports, while a detail is one specific fact used to support that larger point. If an answer choice is too narrow to summarize the whole passage, it is a detail, not the main idea.

Choose the option that follows logically from evidence stated in the passage, even though it is not stated outright. Avoid options that require outside knowledge not supported by the text.

Identify the triggering event and its result, and watch for linking words such as 'because,' 'so,' 'therefore,' and 'as a result,' which usually signal the connection.

Ignore what the word usually means elsewhere and use only the clues in the surrounding sentence to work out its meaning within that specific passage.

Skim the passage first to grasp its overall topic and structure, then read each question and scan back to the relevant section rather than re-reading the whole passage in detail every time.

Look for time-order clue words such as 'first,' 'then,' 'next,' and 'finally,' rather than assuming events happened in the same order they were written about in the passage.

'Apprehend' means to arrest or formally take a suspect into custody. 'Detain' means to hold someone briefly, which is a shorter, less formal process than an arrest.

A formal, sworn statement given as evidence, often in court or during a police investigation.

'Vigilant' means watchful and alert to danger. Its antonym is 'careless' or 'inattentive.'

Look for the option that matches both the meaning and the degree or tone of the original word, not just any loosely related word. A near-synonym that is too strong or too weak is usually a distractor.

Watch for an answer choice that is merely unrelated to the word rather than its true opposite. A genuine antonym directly reverses the original word's meaning.

'Reckless' means acting without regard for danger or consequences, while 'cautious' is close to its opposite, meaning careful and prudent.

Find the common difference between consecutive terms. Here each term increases by 3, so the next number is 11 + 3 = 14.

Count the skip pattern between the letters. Here each letter skips one letter in the alphabet (A, skip B, C, skip D, E...), so the next letter is I.

Identify the relationship in the first pair (an animal and its home), then apply the same relationship to the second pair. A bee's home is a Hive.

Find the shared rule or category that links most of the items together, then identify the single item that breaks that shared rule.

'All' means every single member of a group without exception, while 'some' means at least one member, but not necessarily every member.

Find the constant multiplier between consecutive terms. Here each term is multiplied by 2, so the next term is 24 × 2 = 48.

Write down each clue as a rule, start with the most restrictive clue (the one that fixes an item's position most precisely), then fit the remaining items around it rather than guessing an order first.

Kingston, which is also Jamaica's largest city and the seat of its government.

Jamaica gained independence on August 6, 1962, from the United Kingdom.

Jamaica has 14 parishes, historically grouped into 3 counties: Cornwall, Middlesex, and Surrey.

"Out of Many, One People," reflecting the country's multi-ethnic population.

The national bird is the Doctor Bird (the red-billed streamertail hummingbird, found only in Jamaica), and the national flower is the Lignum Vitae.

The Ackee is Jamaica's national fruit. Combined with saltfish (salted cod), it forms the national dish, ackee and saltfish.

Black represents hardship and strength, green represents hope and the island's vegetation, and gold represents natural wealth and sunshine.

The Jamaican dollar (JMD).

Applicants must generally be between 18 and 30 years of age. The recruiting officer has the authority to waive this guideline based on special circumstances.

At least four subjects at CXC/CSEC grades 1-3 (or an equivalent like GCE O-Level grades A-C), which must include Mathematics (or a math-based subject such as Accounts, Physics, or Chemistry) and English Language.

Minimum height is about 5'7" for men and 5'5" for women, and applicants must meet the JCF's medical, psychological, and physical fitness standards. The recruiting officer may waive the height guideline in special circumstances.

The JCF is headed by the Commissioner of Police and falls under the authority of Jamaica's Ministry of National Security.
