Cambridge B1 Preliminary (PET): The Complete Guide for 2026

If you’re a B1-level English learner — or close to it — someone has probably mentioned the Cambridge B1 Preliminary exam to you, most likely by its older name, PET. It sits one rung below B2 First on the Cambridge English ladder, and it has a reputation for being the “easy one.” It isn’t quite. Every year, plenty of candidates who can hold a decent conversation still miss a Pass, usually because they prepared for the wrong thing. Here’s exactly what’s on the exam, how it’s scored, and how to get ready without wasting months on it.

What Is the Cambridge B1 Preliminary (PET), and Who Is It For?

B1 Preliminary is part of the Cambridge English Qualifications family, which runs A2 Key → B1 Preliminary → B2 First → C1 Advanced → C2 Proficiency. It confirms B1 (intermediate) on the CEFR scale: you can handle everyday situations, give opinions, and get through routine work or study tasks in English, even if you still hesitate on more complex grammar.

Unlike IELTS or TOEFL, it never expires, so it works well as a permanent record for a CV, a school application, or simply as proof to yourself that your English has reached a real, internationally recognised level. There’s also a “B1 Preliminary for Schools” version with the same format and scoring but topics aimed at teenagers — useful to know if you’re choosing an exam for a younger learner.

The Four Papers, Part by Part

Reading (45 minutes)

Six parts, 32 questions. You’ll work through short real-world texts — signs, notices, adverts — as well as longer magazine and online articles, using multiple-choice, matching, and gapped-text tasks. The trap here is timing, not vocabulary: with six parts in 45 minutes, re-reading a whole article three times isn’t an option. Skim the questions before you read, so you know exactly what you’re hunting for.

Writing (45 minutes)

Two parts. Part 1 asks for a short message of around 35–45 words — usually a reply to a friend — that must cover three content points given in the prompt. Part 2 gives you a choice between a short story or an article of about 100 words. The single biggest mark-loser in Part 1 is ignoring one of the three content points: examiners check for all three, and a beautifully written message that’s missing one still loses marks.

Listening (about 36 minutes)

Four parts, 25 questions, each recording played twice. You’ll hear a mix of short everyday exchanges and longer interviews or discussions. Use the two plays strategically: the first pass is for the general gist, the second is for the specific detail the question is actually asking about. Most candidates lose points by trying to catch everything on the first listen and panicking when they miss a word.

Speaking (12–17 minutes, in pairs)

You’re paired with another candidate in front of two examiners — one asks the questions, the other just listens and marks. Four parts: an interview about yourself, a one-minute photo description, a collaborative task where you and your partner discuss and agree on something together, and a short general discussion on the same topic. Part 3 is where nerves do the most damage — candidates either talk over their partner or go quiet. Practising turn-taking phrases like “What do you think?” or “I see your point, but…” out loud, with a real person, is worth more than another week of grammar review.

How PET Is Scored

Results are reported on the Cambridge English Scale, from 120 to 170:

• 160–170: Pass with Merit — your result also certifies B2-level performance.
• 140–159: Pass at B1.
• 120–139: Not a fail — you still receive a certificate, but at A2 level instead of B1.

That last point matters psychologically: there’s no hard pass/fail cliff. Your certificate always states a level, so even an “off” exam day still gives you something official to show.

A Realistic Study Plan

If you’re genuinely sitting at B1 already, six to eight weeks of focused exam practice is usually enough. If you’re closer to A2, budget three to four months to build vocabulary and grammar before switching into exam-format practice — trying to shortcut this stage is the main reason candidates score 120–139 instead of 140+.

A workable weekly rhythm: two sessions of targeted skill work (alternate Reading/Listening one week, Writing the next), one full timed practice test every two weeks, and one lesson with a tutor focused specifically on speaking — it’s the paper that’s hardest to self-correct, since you can’t hear your own hesitations and mistakes the way a trained listener can.

Most B1 candidates spend 90% of their prep time on grammar books and almost none talking out loud under time pressure — so they know the rules but freeze the moment an examiner asks a follow-up question. If you’re not sure whether B1 is realistic yet, Parlazo’s free level test takes about ten minutes and gives you an honest read on where you actually stand. And if you already know your gap is speaking confidence rather than grammar, booking a lesson with one of our native English teachers to run a mock Speaking paper is one of the fastest ways to close it before exam day.
