Cambridge · A2 Key (KET)

A2 Key (KET) Exam Preparation | Cambridge English

An official Cambridge A2 Key certificate, proving basic ability to communicate in everyday situations, with lifetime validity.

Key Takeaways

  • A2 Key (KET) is the entry-level Cambridge English Qualification, proving the ability to communicate in simple, everyday situations.
  • Like every Cambridge English certificate, it never expires — there is no need to retake it or renew it.
  • The exam tests four skills: Reading, Writing, Listening, and Speaking.

A2 Key is often the first formal English certificate a learner earns, confirming the basic communication skills needed for everyday situations such as shopping, travel, and simple conversation. Langcom prepares candidates for the exact tasks and format of each paper, combining live conversational classes with structured exam practice, so the certificate reflects real, usable English rather than memorized exam technique alone.

I was the only one in my school to obtain the Cambridge B2 First certificate while still in primary school in your city. This is a huge advantage for my future studies in your country and abroad, and I won't have to study English again at university. My parents are so proud of me.

Raúl Maguiña

Founder & Teacher, Langcom

I founded Langcom because I watched too many smart, hardworking people — in your country and beyond — spend years and thousands of dollars studying English, only to freeze the moment they had to speak.

The Blended method isn't theory. It's what I wished existed when I was learning English myself — and we built it to be affordable on purpose. Real English education shouldn't be reserved for those who can spend a fortune to access it.

Every plan, every teacher, every certificate we offer carries that promise.

If we can't get you speaking, we haven't done our job.

Langcom's A2 Key preparation is designed and backed by Raúl Maguiña, Director of Asociación Educativa Langcom. Langcom is an Authorized Cambridge English Preparation Centre with over a decade of international teaching experience across 25 countries, combining 100% live instruction with genuine A2 Key exam readiness.

Frequently asked questions

What CEFR level does A2 Key (KET) certify?

A2 Key certifies A2-level English, confirming basic ability to communicate in familiar, everyday situations.

Does the A2 Key certificate expire?

No, like all Cambridge English Qualifications, A2 Key has no expiry date and is valid for life.

What is the Speaking test like for A2 Key?

Candidates take the Speaking test in pairs with two examiners, answering questions individually and interacting briefly with their partner.

What comes after A2 Key?

Most students continue to B1 Preliminary (PET), aligning with Langcom's B1 Pre-Intermediate course.

What happens if I can't attend a live class?

Every group class is recorded and available on your platform within hours. You can also reinforce the material 24/7 with our interactive exercises and AI tutor — so missing one session doesn't slow your progress. If you need a flexible schedule, ask us about Private Classes (you can reschedule and never miss a session).

How long until I can actually speak English?

Depends on your starting point and your plan. Starting from zero with our 3 Courses/Month plan, most students reach strong conversational level (B2/C1) in 12 months and pass Cambridge B2 First by month 14. With 2 Courses/Month, expect 18 months. Faster than every traditional academy in Peru — that's the point of Langcom "Blended" method.

Why is Langcom 4× faster than other academies?

Two reasons. First, the "Flipped Classroom" model: you study grammar and vocabulary on the platform before class, so your live class is 100% speaking — up to 8× more practice per session. Second, the AI tutor lets you practice between classes instead of waiting a week. The result: progress that takes 4 years elsewhere takes up to 9-12 months with us.

Can I cancel or change plans?

Yes, anytime. Upgrade, downgrade or pause month to month — no penalties, no long-term contracts. If you change your mind in the first 7 days, we refund 100%.

Who are the teachers? Are they native speakers?

Our teachers, national and foreigners, are certified bilingual professionals — selected for language mastery (C1/C2 level), teaching credentials, and communicative methodology. Many have international certifications. The goal isn't to study with a native speaker, it's to learn to speak like one — that's what our method delivers.

I've tried other academies and apps. Why will this work for me?

Because the method is built on a different premise: you don't learn a language by memorizing rules — you learn by speaking. Apps like Duolingo give you no live practice. Traditional academies give you 5–12 minutes of speaking per 90-minute class. Langcom gives you up to 8× more speaking time, plus 24/7 self-study, plus a free certificate. 95% of our students pass their international exam on the first try. That's why it works

How is Langcom different from apps like Duolingo or Open English?

Apps like Duolingo are great for casual practice, but they don't include live classes or an internationally-recognized certificate — so you can't prove your level for a job, university or visa. Open English does have live sessions, but they're mass group classes with rotating teachers and no official exam. Langcom gives you structured live classes with the same qualified teacher, a 24/7 AI platform for self-study, and the Cambridge, IELTS, TOEFL or Michigan exam included FREE.
