Learn English from Scratch: A0 to B1 on Your Own

Starting English from zero as an adult is a different challenge than continuing from an intermediate level. You have no vocabulary to fall back on, no grammar scaffolding, and no listening experience. This guide takes you from A0 to B1 using free and low-cost tools, at whatever pace fits your life.

What A0 to B1 Actually Means

Before outlining the path, let’s define the destination clearly.

A0 is zero English. You might know “hello,” “yes,” and “OK” — that’s roughly it.

A1 is functional survival: introducing yourself, asking simple questions, understanding common signs and instructions. About 500–800 word families.

A2 is basic communication: discussing familiar topics, understanding simple instructions, reading simple texts. About 1,000–1,500 word families.

B1 is the independence threshold: traveling to English-speaking countries without a phrasebook, understanding the main points of most texts on familiar topics, participating in simple conversations. About 2,500–4,000 word families.

The total time from A0 to B1 varies significantly by native language. Spanish speakers: 300–400 hours of focused study. Russian, Polish, Turkish speakers: 600–700+ hours. These are realistic estimates for consistent learners, not optimistic marketing claims.

Forty minutes daily gets you to B1 in 18–24 months from A0. One hour daily cuts that to 12–18 months. These are conservative estimates that account for human variability.

Phase 1: A0 to A1 — The Vocabulary Base (Months 1–3)

At A0, you need vocabulary before anything else. Grammar can wait. Speaking can wait. You need enough words to start understanding English when you encounter it.

What to do:

Duolingo or a similar beginner app is actually appropriate here. The gamified format works well at A0–A2 because the vocabulary is controlled and the repetition is built-in. Use it for 15–20 minutes daily as your primary vocabulary source in Phase 1.

Supplement with a basic bilingual dictionary. When you encounter English words — on signs, in products, on your phone — look them up and note them. These incidental encounters add up quickly.

What to learn first (in rough priority order):

1. Numbers, days, months, colors, basic adjectives (100 words)
2. Common verbs: be, have, want, need, go, come, see, know, can, will (50 verbs)
3. Common nouns for everyday life: food, family, work, time, places (200 words)
4. Basic sentence structure: Subject + Verb + Object (I want water, She knows English)
5. Questions: How, What, Where, When, Who + the basic verbs above

You don’t need grammar rules at A0. You need patterns — and patterns come from repeated exposure. Duolingo’s format handles this reasonably well for beginner vocabulary.

Milestone: You can introduce yourself, say where you’re from, name common objects, and count to 100. This is A1.

Phase 2: A1 to A2 — Building Structure (Months 3–8)

At A1, you have basic vocabulary. Now grammar becomes relevant — not as abstract rules, but as tools for saying things you can’t yet say. Two grammar areas matter most at this stage:

Tenses: Present simple (I work), present continuous (I am working), past simple (I worked), future with “will” and “going to.” These four cover the vast majority of everyday communication.

Common question forms: Do you…? Are you…? Have you…? Can you…? Where is…? These are templates you’ll use constantly.

How to study grammar at A1–A2:

Don’t buy a grammar book. Use free resources: BBC Learning English’s grammar section, English Grammar in Use (by Raymond Murphy — the blue book, very accessible, find a used copy), or the British Council LearnEnglish grammar reference. Study each grammar point with examples, then look for that pattern in authentic English over the following week.

Content at A1–A2:

Graded readers at Oxford Bookworms Starter and Level 1 are your reading material. These use controlled vocabulary (400–600 word families) and give you narrative context that makes grammar and vocabulary memorable. Read one short graded reader per week.

Listen to BBC Learning English programs (6 Minute English, English at Work). These are scripted, clearly spoken, and have full transcripts — ideal for A1–A2 listening practice. Listen first without transcript. Then listen again with the transcript. Then read the transcript aloud.

Vocabulary:

Continue building with spaced repetition. By end of A2, target 1,500 word families. Anki with a pre-made A2 vocabulary deck, or continue with Duolingo, works here.

Milestone: You can hold a basic conversation about daily life, understand simple written instructions, and follow simple audio with some vocabulary gaps. This is A2.

Phase 3: A2 to B1 — Moving Into Real English (Months 8–18)

A2 to B1 is the most important transition for most learners. This is where you move from simplified content to real English — and it’s where many learners stall or quit.

The shift at A2: stop relying on graded content and start consuming authentic English, slightly above your current level. The 90% comprehension rule applies: choose material where you understand the vast majority but encounter some new vocabulary.

Reading at A2–B1:

Graded readers at Oxford Bookworms Level 2–3. Authentic texts on topics you know well (articles about your profession, hobby, or country in English). Simple English Wikipedia for topics you’re curious about.

Start transitioning to authentic texts around the B1 mark. A newspaper article about a topic you’re expert in feels manageable even if your English is still B1, because your knowledge of the topic compensates for vocabulary gaps.

Listening at A2–B1:

BBC Learning English remains useful but should feel easier now. Move toward podcasts like Voice of America Learning English (slightly simplified authentic news) and begin watching English-language YouTube with English subtitles.

Subtitles at this stage: English subtitles, not subtitles in your native language. Native-language subtitles let you read rather than listen; English subtitles force you to connect sound to text, which is more useful.

Speaking and Writing:

Start language exchange at A2. Yes, it’s uncomfortable. Yes, you’ll make mistakes. That’s the point. HelloTalk and Tandem (both free) let you connect with native English speakers who want to learn your language. Start with text messaging before voice — the lower pressure of text helps at A2.

Write every day: even three sentences in a diary. The habit of expressing yourself in English, even badly, builds production fluency that reading alone never does.

Grammar focus at B1:

At B1, grammar that matters: conditionals (if I had more time, I would…), passive voice (it was built in 1990), perfect aspects (I have lived here for five years), and reported speech (she said she was tired). These patterns appear constantly in real English. Study one per week, then look for it everywhere.

Milestone: You can read and broadly understand everyday English texts, follow most of a simple English podcast, and have a conversation about familiar topics with occasional vocabulary gaps. This is B1.

Common Mistakes from A0 to B1

Spending months on vocabulary before attempting grammar. You need both simultaneously from A1. Grammar provides the scaffolding that makes vocabulary useful. Don’t sequence them — interleave them.

Waiting until you’re “ready” to use real English. Real English feels hard at A2. That’s normal and expected. Start with easy authentic content (simple news, simple YouTube videos) earlier than feels comfortable. The discomfort is the learning.

Relying solely on an app like Duolingo past A2. Duolingo’s strength is vocabulary drilling and habit formation at beginner levels. Past A2, its controlled format stops challenging you enough. Use it as a supplement, not a primary method.

Treating the native language as the enemy. Bilingual resources at A0–A1 are efficient. Your native language is a scaffolding tool — you’ll need less of it as you progress, but suppressing it entirely at A0 is counterproductive.

Not tracking progress. Without milestones, learners often underestimate how far they’ve come and overestimate how far they have to go. Test yourself monthly with a CEFR-aligned reading or listening exercise. Visible progress sustains motivation.

FAQ

Is A0 to B1 possible without any classes? Yes, many adults do it through self-study. Classes accelerate the process for some learners by providing accountability and instant error feedback, but they are not a requirement.

Should I learn British or American English as a beginner? Either is fine. Choose based on which accent you encounter more in your life. Consistency matters more than which variety — don’t mix deliberately, but don’t stress about encountering both.

I studied English in school years ago and remember almost nothing. Am I A0? Probably A2 with some dormant knowledge. Take a placement test. Your school English will likely come back faster than you expect once you start — the brain doesn’t forget as completely as it seems.

Is it too late to start learning English as an adult? No. Adult learners have worse implicit pronunciation acquisition but better explicit learning efficiency than children. Adults can reach B2 in the same time or faster than children who start from the same A0 baseline, under comparable study conditions.

What’s the most efficient single thing I can do to go from A0 to B1? Daily vocabulary review with spaced repetition, combined with daily comprehensible input (graded readers early, authentic texts later). The combination of building vocabulary and encountering it in context is what drives the fastest A0–B1 progression.

How long should I use Duolingo? Use it as your primary vocabulary tool through A1–A2. By B1, you should be spending more time with authentic content than with gamified exercises. Keep it as a warm-up if you enjoy it, but don’t let it crowd out real reading and listening.

The Path Summarized

A0 to A1: vocabulary foundation (500 words, basic patterns), 15–20 minutes daily on Duolingo or a similar tool. A1 to A2: grammar structure (tenses, question forms) + graded readers + BBC Learning English. A2 to B1: authentic content at appropriate level + speaking practice + writing daily.

Each phase builds on the previous one. The tools change; the core habit — daily contact with English — doesn’t.

Start with what you have, from where you are. B1 is not a distant goal — it’s the result of months of showing up.
