CELPIP rarely repeats wording. It tests whether you can match the same idea expressed with new words—without changing:
- Strength (must/should/may),
- Scope (who/when/how many),
- Polarity (positive vs negative).
Your job is to separate safe paraphrases (meaning preserved) from false friends (meaning shifted).
Think of every option as three switches you must keep in the same position as the passage.
-
Strength (degree/modality)
- must / required / mandatory → strongest
- should / expected / advised → medium
- may / might / could / allowed to → soft
-
Scope (who/where/when/how many)
- all / every / always → widest
- most / usually / generally
- some / often / sometimes
- few / rarely / hardly ever → narrowest
-
Polarity (yes/no and time logic)
- not / except / unless / only
- Time toggles: before / after / by / until / from / starting
If an option changes any switch, it’s wrong even if the topic matches.
These swaps keep the idea the same when strength/scope/polarity also match.
- Cause & effect: because → due to / owing to / as a result of; therefore → so / thus / hence
- Contrast: however → but / nevertheless / even so / whereas / on the other hand
- Addition: and → also / in addition / furthermore
- Condition: if → provided (that) / as long as / on condition that
- Purpose: to / in order to → so that / for the purpose of
- Examples: for example → for instance / such as / including
- Result size: increase → rise / grow / go up; decrease → drop / decline / fall
- Money/time neutral: cost → fee / charge; free → at no charge; schedule → timetable / roster
Safe role swaps
- residents ↔ people who live here
- staff ↔ employees ↔ personnel
- supervisor ↔ manager (context-dependent but often neutral)
Memorize these; they cause most mistakes.
- must / required ≠ should / recommended
- will ≠ may / might
- free ≠ discounted / reduced
- exactly ≠ at least
- by 5 pm (≤ 5:00) ≠ until 5 pm (time period ends at 5:00; not after)
- not until 5 pm (nothing before 5:00) ≠ no later than 5 pm (any time up to 5:00)
- only (restrictive) ≠ especially (emphasis)
- some (at least one) ≠ most (more than half)
- can (ability/permission) ≠ should (advice) ≠ must (obligation)
- before 6 pm → any time < 6:00
- after 6 pm → any time > 6:00 (often 6:01+)
- from 6 pm → includes 6:00
- by 6 pm / no later than 6 pm → ≤ 6:00
- until 6 pm → up to 6:00, not after
- between 2–4 pm → usually inclusive unless a note says otherwise
- weekdays = Mon–Fri; weekends = Sat–Sun (don’t mix Friday evening with weekend rules)
- noon = 12:00 pm; midnight = 12:00 am
Write the time logic into your notes before you scan.
- at least 3 → 3, 4, 5…
- at most 3 → 3, 2, 1, 0
- fewer than 3 → 0, 1, 2
- more than 3 → 4, 5…
- up to 3 → usually ≤ 3 (not guaranteed to be 3)
- no more than 20% → ≤ 20% (don’t confuse with “20 percentage points”)
Comparatives need a baseline: higher than last year, more lanes than in the morning. If the baseline changes, the meaning changes.
When a word is unfamiliar, break it into prefix + root + suffix.
Prefixes (direction/amount)
- pre- (before), post- (after), re- (again), non- (not), un-/in-/im- (not), over- (too much), under- (too little), mis- (wrongly), anti- (against), pro- (for), inter- (between), sub- (under)
Common roots
- spect (look), scrib/script/graph (write), port (carry), tract (pull), form (shape), cred (believe), bio (life), geo (earth), chron (time), therm (heat), meter (measure)
Suffixes
- -tion / -ment / -ance (noun: action/state), -er / -or (person/thing), -able / -ible (can be), -less (without), -ful (full of), -ish (somewhat), -wise (in terms of), -ward(s) (direction)
Example: misallocation → mis (wrong) + alloc (assign) + ation (act) → “wrong assignment.”
CELPIP leans on everyday phrasal verbs. Know the plain-English version.
- pick up (collect), drop off (deliver/leave), fill out (complete a form), turn in (submit), set up (arrange), call off (cancel), look into (investigate), work out (resolve), put off (postpone), run into (encounter), roll out (launch), opt out (decline), top up (add credit), phase out (gradually stop)
If an option replaces a phrasal verb with a different action (cancel vs postpone), that’s a meaning shift—reject it.
- Cause: because, since, due to, as
- Contrast: but, however, whereas, despite, although, even though
- Sequence: first, then, after, later, meanwhile, subsequently
- Condition: if, unless, provided that, as long as
- Purpose: to, in order to, so that
- Concession: even if, even though, granted, admittedly
Questions that ask “Why did…?” or “What is the writer’s purpose?” often hide the answer behind these connectors. Match connector function, not just words.
Everyday collocations by topic (CELPIP-style texts)
Community & city services
- apply for a permit, file a complaint, request a refund, issue a notice, road closure, detour route, garbage pickup, recycling schedule, noise bylaw, property tax
Transport & facilities
- peak/off-peak hours, lane reduction, service outage, fare zone, valid only on, transfer policy, delay due to weather, accessible entrance
Housing & building
- maintenance request, elevator outage, lease renewal, damage deposit, move-in inspection, parking pass, guest policy, pet restrictions
Work & appointments
- business hours, walk-in welcome, by appointment, ID required, reschedule for, deadline extended, training session, orientation
Health & community programs
- eligibility criteria, waitlist, drop-in class, vaccination clinic, proof of address, coverage limit, referral required
Library & education
- overdue fines, hold a book, renew materials, study rooms, orientation session, placement test, enrolment cap
These pairings appear in emails, notices, brochures, and diagrams. Recognizing them lets you read faster and avoid awkward paraphrase traps.
- Swap-back test: Replace the option’s phrase with the passage’s phrase (or a safe paraphrase). Does the sentence still mean the same thing?
- Switches check: Strength / Scope / Polarity must match exactly.
- Anchor proof: Point to the line, table cell, or footnote that supports it. If you can’t touch the words, it’s not safe.
- Tone sanity: For replies/comments, the register (formal/neutral/friendly) must match the original.
One failed step → eliminate.
- Strength ladder: must → should → may
- Scope ladder: all → most → some → few
- Polarity toggles: only / except / unless / not until / by / until / from
- Time traps: by vs until; after vs from; noon vs midnight; weekday vs weekend
- False friends: must≠should; will≠may; free≠discounted; exactly≠at least
If an option “sounds right,” but one switch moves, it isn’t right. Match idea and control the switches—your accuracy jumps immediately.
