Cambridge B1 Exam Simulator

I've prepped a lot of students for B1 Preliminary, and this is the app I keep coming back to. The Cambridge B1 Exam Simulator drops you straight into the real PET environment: same timing, same layout, same pressure. You get unlimited full-length Reading, Use of English, and Listening papers, so exam day stops feeling like a mystery and starts feeling like Tuesday.

My honest take on the Cambridge B1 Exam Simulator

I'll be upfront: I'm picky about exam-prep tools, and most of them either look pretty or actually work. This one, built by TCK Systems LLC, sits firmly in the second camp. It's a B1 Preliminary (PET) simulator, which means everything is tuned to the Preliminary English Test rather than some vague "intermediate" bucket. When I first opened it, the thing that struck me was how closely the interface mirrors the official Cambridge Assessment English format. That familiarity matters more than people think. Half the battle at B1 is not panicking when the clock starts.

The full-length simulations are the heart of it

You get unlimited Reading, Use of English, and Listening papers, and they run at real exam length and real exam timing. No trial caps, no "you've used your three free tests this week" nonsense. I used them to build stamina, which is the quiet skill nobody talks about. By the fifth or sixth full paper, sitting still and focused for the whole thing just felt normal. That's exactly what you want walking into the actual PET.

Focus Zone for your weak spots

When you don't have time for a whole paper, the Focus Zone lets you isolate a single part, say Reading Part 1 or Listening Part 3, and drill just that. I love this for targeted repair work. If a student keeps losing marks on one task type, we hammer that part until the pattern clicks, instead of burning an hour on a full mock to practice ten minutes of weakness.

Reels practice for the in-between moments

There's an infinite-scroll Reels feed of mini-exercises covering grammar, vocabulary, and verb conjugations. It sounds gimmicky, and I expected to hate it. I didn't. It's genuinely good for keeping English ticking over in a bus queue or a coffee break, and it keeps phrasal verbs and everyday vocabulary fresh without the weight of a full test.

Feedback that actually explains things

Every question comes with Extended Feedback. This is where the app earns its keep for me. Instead of a bare "wrong," you get a proper explanation of why the correct answer is correct, which is the difference between memorising an answer and understanding the grammar behind it. The content was built by data engineers and checked by real English teachers, and you can feel that combination in how the explanations are worded.

• Unlimited PET simulations: full-length Reading, Use of English, and Listening papers with no practice caps, matching official B1 Preliminary timing.
• The Focus Zone: isolate individual exam parts to strengthen specific weak points fast.
• Extended Feedback: clear, detailed explanations on every answer so you learn the reasoning, not just the result.
• Reels practice: an endless feed of grammar, vocabulary, and verb-conjugation micro-tasks for daily habit-building.
• Progress tracking: visual analytics that show your scores climbing, which is oddly motivating when momentum dips.
• Web sync: your account carries over to the web platform at cambridgexam.com, so you can switch between phone and laptop without losing your place.

Who I'd recommend it to

If you're a few weeks out from your B1 exam and want to stop guessing what the paper feels like, this is the tool. It's equally good for learners just stepping up from A2 who want a structured on-ramp into Preliminary English Test practice. Between the realistic simulations, the surgical Focus Zone drilling, and feedback that treats you like someone who wants to actually improve, it's become my default recommendation for PET candidates. Available on iOS and Android, with packages for schools if you're a teacher running a class.
