The short answer
Cambridge English estimates about 500 to 600 guided hours to reach B2 from complete beginner, and about 200 hours for each level along the way. Divide the hours you still need by the hours you can give each week, add a margin, and you have your timeline.
The hours Cambridge English gives
Cambridge English publishes guided learning hours for each level of the Common European Framework of Reference (CEFR), the scale that runs from A1 to C2. Guided hours are the time you spend learning under the guidance of a teacher, and the figures are counted from complete beginner. They are cumulative: the hours for B2 include everything you needed for A2 and B1 before it.
| Level | Approximate guided hours from beginner |
|---|---|
| A2 | about 180 to 200 hours |
| B1 | about 350 to 400 hours |
| B2 | about 500 to 600 hours |
| C1 | about 700 to 800 hours |
| C2 | about 1,000 to 1,200 hours |
Source: Cambridge English. Cumulative and approximate, a guideline only: background, intensity, age and practice outside class all change the real figure.
Read the table as a range, not a promise. Cambridge itself calls these numbers a guideline only, and it lists the things that move them: your language learning background, how intensely you study, your age and how much you study or hear English outside your lessons. Two people in the same class can need very different numbers of hours to reach the same level, and both can be perfectly normal.
The table also shows something encouraging. The gap between levels is roughly the same size all the way up, about 200 hours, a little less at the start and a little more near the top. So the question is rarely "how long to learn English", which has no finish line, but "how long from where I am to the level I need", which you can actually plan.
Guided hours are not the same as self-study
It helps to be clear about what a guided hour is. It is time with a direction: a class with a teacher, or work your teacher sets and then checks. An hour scrolling through English videos with no plan is useful exposure, but it is not the same kind of hour, and the Cambridge figures are not built on it.
That does not make independent practice worthless. Quite the opposite: Cambridge names study and exposure outside lesson time as one of the things that change how long a level takes. The practical way to see it is that guided hours set the route and outside practice decides how fast you travel along it. A learner who only attends classes and a learner who also reads, listens and reviews words every day may sit in the same lessons, but they will not move at the same speed.
Count your hours honestly
When you plan, count classes and the work your teacher sets as guided hours. Count films, podcasts and reading for fun separately, as a bonus that speeds you up, not as hours you can bank against the table.
What changes your real time
Your first language
If your first language shares a lot of vocabulary and grammar with English, you start with an advantage. Speakers of Romance and Germanic languages, such as Spanish, Italian, French, Portuguese or German, recognize many English words from day one, and plenty of sentence patterns feel familiar. Speakers of languages that are further from English have more to build from scratch, from the alphabet in some cases to word order and sounds. Neither group is better at languages; one simply has a longer road.
Other languages you already know
Every language you have learned before teaches you how to learn the next one. You already know what it feels like to not understand everything, you have habits for learning words, and you are used to noticing grammar. People who speak two or three languages often move through the early levels of a new one faster for that reason alone.
Age
Cambridge lists age as a factor, and it cuts both ways. Adults usually bring study habits, patience with grammar and a clear reason to learn, which makes the early levels efficient. Pronunciation, on the other hand, often takes more conscious practice for adults than for children. It is never too late to learn English well; it just pays to spend some of your hours on listening and speaking, not only on rules.
Intensity
Ten hours a week gets you to the same number of hours faster than two hours a week, of course. But intensity also changes how much you keep. A very intensive month can be followed by weeks of forgetting if nothing follows it, while a steady rhythm builds on itself. We come back to this below, because it is the choice most people have to make.
Practice and exposure outside class
This is the factor you control most. Reviewing the words from your last class, doing short exercises, reading a few pages, listening to something you enjoy: all of it keeps English active between lessons. Two learners with the same schedule of classes can end up a whole level apart after a year, and the difference is usually what happened on the days without a class.
From hours to weeks: a worked example
To turn the table into a plan, start with the hours for your goal level, take away the hours for your current level, and divide the rest by the hours you can give each week. To keep the arithmetic simple, the example below uses the middle of each Cambridge range: B1 about 375 hours, B2 about 550 and C1 about 750. That makes B1 to B2 about 175 more guided hours, and B2 to C1 about 200.
Now take four realistic weeks. A light week is two classes of an hour and a half, three hours in all. A standard week adds homework and exercises for about five hours. A committed week adds a little practice every day for about eight hours. An intensive week, such as a course during a summer break, can reach fifteen.
| Weekly schedule | Hours a week | B1 to B2 (about 175 hours) | B2 to C1 (about 200 hours) |
|---|---|---|---|
| Two classes | 3 | about 58 weeks | about 67 weeks |
| Classes and homework | 5 | about 35 weeks | about 40 weeks |
| Classes, homework and daily practice | 8 | about 22 weeks | about 25 weeks |
| Intensive course | 15 | about 12 weeks | about 13 weeks |
Hours divided by hours per week, rounded to the nearest week. Based on the middle of the Cambridge ranges; your own figure can sit well above or below it.
The table makes one thing very visible: going from three to five hours a week saves more than five months on the way from B1 to B2. Small, regular additions, such as twenty minutes of review on the days between classes, change the result far more than people expect.
Add a margin
Real years have holidays, busy months at work and weeks when you are ill. Add about a fifth to whatever number you get, and you will have a plan you can keep without feeling behind.
Not sure which level you are?
The level test places you from A1 to C1 in a few minutes, and shows the class that fits you.
Intensive or steady?
Most people end up choosing between a short, intensive push and a longer, steady rhythm. Both work, and they suit different situations.
Intensive
Many hours a week for a few weeks or months. It suits a fixed deadline, such as an exam date or a move abroad, and it gives you a strong sense of progress. The risk is what comes after: without regular practice to follow it, part of what you gained fades.
Steady
A few hours every week, on fixed days, for as long as it takes. It is slower on paper, but it fits around work and family, it builds a habit, and the spacing between sessions helps memory. For most adults it is the rhythm that lasts.
You can also combine them: a steady rhythm for most of the year and an intensive block before an exam or a trip. What matters is that the rhythm after the intensive block is one you can keep.
What speeds learning up
Spaced review
Memory research has shown for decades that reviewing material spread out over time works better than going over it many times in one sitting. A large review of studies on this spacing effect, published by Cepeda and colleagues in Psychological Bulletin in 2006, found the same pattern across many experiments with words and facts. For language learners, that means seeing a new word again after a day, then a few days, then a week, rather than reading a list ten times the night before a test. Flashcards that bring back the words from your own classes at the right moment do exactly that.
Recalling, not rereading
A related finding is that trying to recall something strengthens memory more than reading it again. Roediger and Karpicke showed this in a well-known 2006 study in Psychological Science: students who tested themselves remembered more a week later than students who simply studied the text again. In practice, cover the answer, say the word or the sentence yourself, and only then check. Short exercises with instant feedback work the same way.
Speaking from day one
Reading and grammar exercises move quickly on your own, but speaking only improves by speaking. Waiting until you "know enough" to speak is one of the most common ways to lose time. Live classes in a small group give you many turns to talk, and you hear different voices and different ways of saying the same thing, which is exactly what real conversations are like.
Feedback
Practice without feedback can quietly fix mistakes in place. When a teacher corrects your homework, you see which errors you make again and again, and you can work on those instead of guessing. Exercises that tell you at once whether an answer is right close the loop in seconds, so you do not practice the wrong form for a week.
A consistent schedule
Classes on fixed days, with the same teacher and the same small group, take the decision out of studying. You do not have to find the motivation every evening; the time is already there, and so are the people expecting you. Habits like this are what keep the hours coming in month after month.

Listening and reading
You learn a great deal of English simply by understanding it. Listening and reading give you words in context, natural word order and the rhythm of the language, all without the pressure of producing it. Choose material that is only slightly above your level: if you understand most of it, you will pick up the rest from context. Podcasts on your commute, short articles on topics you like and series with English subtitles all count.

A few hours every week, every week, is what gets you there.
The intermediate plateau
Many learners move quickly through A1, A2 and the start of B1, then feel that progress stops. They can get by, they understand a lot, and yet nothing seems to change for months. Language teachers know this so well that it has a name, the intermediate plateau; Jack C. Richards wrote a whole booklet about it for Cambridge University Press, Moving Beyond the Plateau.
Part of the reason is that the plateau is partly an illusion. At the beginning every week brings words you use every day, so progress is easy to feel. Between B1 and B2 the new material is subtler: more precise vocabulary, natural phrases, tenses used with more nuance. You are still learning, but each step feels smaller. The other part is real: once you can communicate, it is tempting to keep using the same safe words and structures, and the language you avoid never grows.
Moving past it usually means pushing your output, not only your input. Write a little more than you need to, and have it corrected. In class, try the structure you would normally avoid. Keep a notebook of phrases you meet in reading and listening, and use them on purpose the following week. Set yourself goals that are specific enough to check, such as following a podcast without pausing or writing an email to a colleague without a dictionary.

Change the task, not just the hours
If months of the same routine have stopped moving you, more of the same will not help much. Add writing with corrections and speaking about topics outside your comfort zone, and the next level comes back into view.
Realistic goals by purpose
Travel
For travel, B1 is a good target. The Council of Europe describes a B1 learner as someone who can deal with most situations likely to arise while traveling in an area where the language is spoken. Even A2 lets you handle simple, routine exchanges such as ordering, asking for directions and checking in. From complete beginner, the Cambridge table puts B1 at roughly 350 to 400 guided hours; at five hours a week, that is well over a year, so start early if a trip is your reason.
Work
Many jobs that use English every day ask for B2. At B2, according to the CEFR, you can interact with a degree of fluency and spontaneity that makes regular conversation with native speakers possible without strain for either side. For presentations, negotiation or writing reports, C1, where you use the language flexibly and effectively for social, academic and professional purposes, is often the more comfortable level. Check what your employer or the job advertisement actually asks for, and plan from there.
Exams
An exam gives you a fixed date, which makes planning easier. Start from the score your university, employer or visa office requires, find out your current level, and work backward from the exam date to the hours you need each week. Leave time at the end to practice the exam format itself, because knowing how each paper works is a skill of its own. If you need a certificate such as B2 First, C1 Advanced or IELTS, practice in that format well before the day.

Whatever your purpose, a lot of the extra practice can happen on the go. Reviewing flashcards on the bus, doing a short exercise while you wait, or listening to an episode on a walk all add minutes that become hours by the end of the month.
How to estimate your own timeline
Start by finding out where you are. A level test takes a few minutes and places you on the scale; at Alimun it goes from A1 to C1. Then decide where you need to be and by when, using the purposes above as a guide. Look up the gap in the Cambridge table, and be honest about how many hours a week you can give, counting classes and the work your teacher sets.
Divide the gap by your weekly hours and add a margin for real life. If the result is later than your deadline, you have three options: add hours, lower the target for now, or move the date. If it is earlier, good: use the extra time for listening, reading and speaking, which will make the level you reach feel more solid.
Finally, check your plan every few months. If you are moving faster than the table, enjoy it; if you are slower, look at the factors above before you add hours, because sometimes changing the kind of practice helps more than adding more of it.

Questions people ask
Can I learn English in three months?
You can make clear progress in three months, especially with several hours a week. Going up a whole level usually takes longer: at about 200 guided hours per level, three months means around 15 hours a week, which is an intensive course.
Do hours on an app count?
Any practice helps, and spaced review and short exercises are genuinely useful. The Cambridge figures, though, refer to guided learning with a teacher, so apps work best alongside classes, as the practice that speeds you up between them.
Is it harder to learn English as an adult?
Not harder, just different. Adults often learn grammar and vocabulary efficiently thanks to their study habits and what they already know. Pronunciation can take more conscious practice, so give listening and speaking a regular place in your week.
Why do I feel stuck at B1?
Many learners hit an intermediate plateau. Progress becomes less visible, and it is easy to keep using the same safe language. Writing more with corrections, speaking about less familiar topics and using new phrases on purpose usually gets things moving again.
How do I know my current level?
Take a level test. The one at Alimun places you from A1 to C1 in a few minutes, and from there the Cambridge table shows roughly how far you have to go.
