‘How many weeks will it take?’ is a fair question when you are planning time and money for a course in the UK. Some schools are tempted to give a confident number. The honest answer is that it depends on the learner, but there are reliable rough guides that help you plan sensibly and avoid disappointment.
Levels first: understanding the CEFR
Most schools and exams describe English ability using the Common European Framework of Reference for Languages (CEFR). It has six levels in three bands: A1 and A2 (basic user), B1 and B2 (independent user), and C1 and C2 (proficient user).
- B1: you can deal with most everyday and travel situations and talk about familiar topics.
- B2: you can follow the main ideas of complex texts and talk fluently with native speakers without strain on either side.
- C1: you can understand long, demanding texts and express yourself fluently and flexibly for social, academic and professional purposes.
These levels matter beyond the classroom. For example, GOV.UK asks for B2 for a Student visa at degree level and B1 below degree level.
A rough guide: guided learning hours
Cambridge English publishes guidance on the ‘guided learning hours’ a learner typically needs, meaning time spent learning with a teacher’s support. It suggests that moving up one CEFR level takes approximately 200 hours. Its approximate totals, counted from complete beginner, are:
- A2: 180 to 200 hours
- B1: 350 to 400 hours
- B2: 500 to 600 hours
- C1: 700 to 800 hours
- C2: 1,000 to 1,200 hours
Cambridge stresses that these figures are a guideline only. The factors that make the difference, it says, include your language learning background, how intensively you study, your age and how much English you study or hear outside lessons.
Turning hours into weeks
You can use these figures for a rough estimate. First, find out how many hours of actual teaching a course offers each week, not the number of ‘lessons’, which can be shorter than an hour. Then compare that with the gap between levels. For instance, a student who is securely at B1 and needs B2 is looking at roughly 200 guided hours on the Cambridge guide, plus regular practice.
For example, if a course gives 15 hours of teaching a week, ten weeks adds up to about 150 guided hours. On the Cambridge guide, that is a meaningful step but probably not a full level on its own. An intensive course with more hours, plus genuine practice outside class, moves faster. Treat any calculation like this as a planning tool, not a promise.
Why progress feels uneven
Learners often notice quick gains at the start, especially in listening and confidence, then a slower stretch around the intermediate levels. This is normal. The step from B2 to C1 involves more precise vocabulary, academic writing and subtle listening, and it often feels slow even when progress is steady.
Skills also move at different speeds. A student may speak fluently after a few weeks in a homestay but need much longer to write a strong essay. If you have an exam target with a minimum score in each skill, plan around the weakest one.
Age plays a part too, in different ways. Younger learners often pick up everyday speech and pronunciation naturally through immersion, while adults usually make quicker use of grammar explanations and study strategies. Nobody is too young or too old to make real progress; the plan simply looks different.
How to make each week count
- Take a placement test before you book, so the estimate starts from your real level.
- Match the course type to your goal; our guide to general, intensive and exam courses explains the options.
- Use English outside class every day: with your hosts or housemates, with classmates, and through films, podcasts and the news.
- Ask the school how progress is measured, and request regular feedback.
- Agree a mid-course check with the school, so that if progress is slower than planned you can adjust the course or timeline early.
- Plan practice for after the course, so the gains last.
If an exam is the target, leave a margin for a retake. Our article on choosing between IELTS, Cambridge and PTE may also help.
How YES can help
We look at the student’s current level, goal and available time, and help you plan a course length that is realistic rather than hopeful. If the gap is large, we will say so honestly and suggest a step-by-step plan. Learn more about our language school service or contact us.
Questions families ask
Can my child go from B1 to C1 in one summer?
For most learners that is unlikely. Cambridge English guidance suggests roughly 200 guided learning hours per CEFR level, so two levels is a long-term goal rather than a summer target.
Is a longer course always better value?
Not necessarily. Progress depends on teaching hours, how much English the student uses outside class and their motivation, so a well-planned shorter course can achieve more than a long one with little practice.
How will we know if progress is being made?
Ask the school how it tests progress and how often you will receive reports. Regular feedback on each skill is more useful than a single end-of-course grade.
