Four passages that get progressively less literal. Time runs out in Part 4, so the budget you set in Part 1 decides your band.

1

Part 1 — Correspondence

≈11 min · 11 questions

Reading a personal letter, then completing a reply to it.

The trap

The second half is filled from the reply’s logic, not the letter’s wording. Candidates who keep re-scanning the letter lose the time they need for Part 4.

Read the guide
2

Part 2 — Diagram

≈9 min · 8 questions

Matching a message against a diagram, floor plan or schedule.

The trap

Two options usually fit the picture. Only one fits what the message actually asks for — read the request again before choosing.

Read the guide
3

Part 3 — Information

≈10 min · 9 questions

Scanning a factual passage split into labelled paragraphs and placing each statement.

The trap

"Not given" is a real answer and it is deliberately uncomfortable. If the passage does not say it, do not reason your way there.

Read the guide
4

Part 4 — Viewpoints

≈13 min · 10 questions

An opinion article plus a reader’s comment responding to it.

The trap

Half the questions are about the comment, not the article — and this is exactly where the clock runs out. Bank time in Parts 1–3.

Read the guide

Every part above is in the free practice bank.

No sign-up for Reading. Instant CLB estimate.

How it works

Three steps. The whole loop in under a minute.

Capture once. Review on autopilot. Use the words in real life. FlexiLingo is built around the content you already consume — not another textbook to slog through.

01

Capture

Click any word in a YouTube subtitle, in a podcast transcript, on a webpage, or in a photo from your phone. FlexiLingo grabs the translation, the sentence context, and the difficulty level (CEFR A1–C2).

Review

Saved words land in your deck and surface again at the perfect interval. Pick the spaced-repetition algorithm that fits you — Leitner, SM-2, or FSRS — none of that one-size-fits-all stuff.

Practice typing, hear native pronunciation, and rehearse the words in context. Decks follow you on browser, phone, and desktop, so the next time you see the word in the wild, you know it.
