Prepare for Cambridge using the real exam format
Our Exam Readiness Score tracks your performance on real mock exams and helps you decide when to sit the test.
Exam fees cost €200 — don't spend them without knowing where you stand.
The real problems of preparing for Cambridge alone vs What Lunvello does differently
The real problems of preparing for Cambridge alone
You don't know if you're ready: You study for weeks but have no objective way to measure your level against the exam.
Generic apps don't prepare exams: General vocabulary isn't the same as Key Word Transformation or a 250-word Essay.
Tutors help, but they're expensive: €30-50/hour. Preparing with an academy can cost €600-900.
The exam costs €200 and it's non-refundable: Sitting it without clear data on your level is an expensive gamble.
What Lunvello does differently
Real visibility on your level: Your Exam Readiness Score combines practice volume, accuracy, and exercise variety to guide you on when to sit the exam.
Identical exam format: Every exercise replicates the structure, types, and difficulty of B2 First or C1 Advanced.
Feedback by Cambridge criteria: Your Writings are evaluated on Content, Communicative Achievement, Organisation and Language — the same 4 criteria real examiners use.
Unlimited practice from €16.66/month: A full quarter of premium preparation for less than 2 hours with a tutor.

Key Word Transformation — B2 First
Complete the second sentence so that it has a similar meaning to the first. Use the keyword in bold (2–5 words).
“I haven't seen her for three years.”
The last time I her was three years ago.

Frequently asked questions
What you need to know before getting started.
Can I prepare for Cambridge with just the free plan?
The free plan gives you access to Reading and your Exam Readiness Score — enough to try the product. For real preparation (Writing with 4 criteria, Speaking, Listening, AI Tutor, unlimited exercises), you'll need Cambridge Prep.
Which levels are available?
B2 First (FCE) and C1 Advanced (CAE). You can switch levels anytime from your dashboard.
How long do I need to prepare?
It depends on your starting level. With regular practice (20-30 min/day), many students reach good readiness in 3-6 months. Your Exam Readiness Score will guide you.
Is the Writing correction reliable?
We evaluate each Writing using the 4 official Cambridge criteria: Content, Communicative Achievement, Organisation, and Language. The AI is trained on Cambridge band descriptors. It doesn't replace a certified examiner, but gives you detailed, consistent feedback to improve.
How does AI Speaking work?
You practise all 4 Cambridge Speaking parts talking with AI. You get evaluation on fluency, pronunciation, grammar, and vocabulary. It's real practice with feedback — not a generic chatbot.

Who's behind Lunvello
I'm Roberto, software engineer and founder of Lunvello. I built this platform because when I was preparing for my Cambridge exam, I realised there was no tool that combined the real exam format with specific criteria-based feedback. Lunvello is that product — built with obsessive attention to detail and improved every week.
