How long does it take to improve your English?

Timelines · 2 min read · updated 2026-08-22

Language schools quote hours; apps quote streaks. Neither answers the question people actually ask, which is "how long until I can do the thing I need to do?" Here are honest numbers.

The hours behind each level

The widely used estimates for moving up one CEFR level with study and practice:

• A1 → A2: 80-100 hours
• A2 → B1: 150-200 hours
• B1 → B2: 200-250 hours
• B2 → C1: 250-350 hours
• C1 → C2: 400+ hours, and increasingly about reading and writing rather than lessons

Those are total learning hours, not lesson hours. A lesson is the part that fixes what you cannot fix alone; the rest is exposure — reading, listening, using the language.

What that means in weeks

Two 50-minute lessons a week is about 85 lesson hours a year. Add three hours a week of your own reading and listening and you are at roughly 240 hours a year, which is about one CEFR level for most adults at B1 and above. Faster is possible, and it comes almost entirely from doing more outside the lessons.

The timelines people really want

• "Stop freezing when I speak" — 4-8 weeks of twice-weekly conversation lessons. This
• "Handle meetings at work" — 8-12 weeks, if the lessons rehearse your actual
• "Get through an interview" — 2-3 weeks and 3-5 lessons of mock interviews for a
• "Half a band on IELTS" — 4-6 weeks, mostly on writing and speaking technique.
• "Sound less flat / be easier to understand" — 6-10 weeks of focused pronunciation

The three things that change the timeline most

1. Frequency beats duration. Two 50-minute lessons a week beat one 100-minute lesson, every time. Less warm-up, more retrieval, more chances to notice a mistake between lessons. 2. Speaking time in the lesson. If the teacher talks for 70% of the hour, you are buying listening practice at a speaking price. 3. What happens between lessons. Twenty minutes a day of something you would do anyway in your own language — news, a podcast, a show without subtitles — roughly doubles the effect of the lessons.

How to tell it is working before the level changes

Levels move slowly; symptoms move fast. Within a month you should notice:

• You hesitate in different places than before.
• You catch your own mistakes mid-sentence.
• You need fewer detours around words you do not know.
• You are tired after a lesson for a different reason — thinking, not stress.

If none of that is happening after six weeks, change something: the frequency, the teacher, or what you do between lessons. Tutors here charge from $5 to $26 an hour, so changing is cheap; not changing is what costs.
