Search this question and you’ll find a lot of confident-sounding numbers — “600 hours,” “1,000 hours,” sometimes cited with no source at all. The honest starting point is that no exam body publishes a single official “hours to B2” figure, because actual time-to-level varies hugely by learner. What the Goethe-Institut does publish is how it structures its own courses, and that data lets you build a defensible range instead of repeating an unsourced number.
What Goethe-Institut’s own course structure tells us
On its India course pages, Goethe-Institut lists its A1 through B2.2 classroom courses as running in blocks of 160 teaching units — each unit 45 minutes, so roughly 120 hours per block — delivered across anywhere from 7 weeks (at a superintensive 25 lessons a week) to 20 weeks (at a standard 8 lessons a week). Its worldwide intensive-course format runs 75 lessons over 15 course days, roughly three weeks per level. Its self-paced online option, spanning A1 through C1, is listed at approximately 70–85 hours of total learning time with a recommended 6–7 hours per week. These are course-length figures, not a research-backed “hours to fluency” study — but they’re the closest thing to an authoritative number that actually exists, because they represent what the organisation that helped design the CEFR exam standard considers a realistic course length for its own students.
Turning that into a range for B2
Reaching B2 from zero means passing through four levels — A1, A2, B1, B2 — not one. If each level requires something in the neighbourhood of the 120-hour block Goethe-Institut’s own India courses use, a genuine zero-to-B2 journey lands in the rough range of 480 to 700-plus hours, depending on your starting pace, prior language background, and how much of that time is structured class versus independent practice. We’re presenting this as a range deliberately — a single number like “600 hours” implies a precision that doesn’t actually exist in the underlying data, and treating it as gospel sets up unrealistic expectations either way.
Why the range is so wide
Three things move you toward the lower or higher end of that range. First, prior exposure — someone who already speaks a Germanic or grammatically similar language, or who’s studied another foreign language seriously, tends to move faster than a true beginner. Second, intensity — the superintensive 25-lessons-a-week pace Goethe-Institut itself offers compresses the same total hours into fewer weeks, but requires far more sustained daily effort than a once-a-week evening class ever could. Third, consistency — hours spread out with long gaps between them are worth less than the same hours studied continuously, because retention drops during breaks and earlier material has to be partially relearned.
What this means for planning your own timeline
If you’re mapping this onto a real deadline — for a visa application, or a training start date — treat the lower end of the range (roughly 480 hours) as achievable only with consistent, near-daily study, and the higher end (700-plus hours) as more realistic if your weekly hours are modest or interrupted. We’ve applied this same range directly to a 12-month plan in how to go from A1 to B2 in 12 months, including what weekly hour commitment that timeline actually requires.
Hours alone aren’t the whole picture
Raw hours logged and exam-ready proficiency aren’t automatically the same thing — how those hours are spent matters as much as how many there are. A study plan that neglects speaking practice, for instance, can rack up hundreds of hours of reading and vocabulary work and still leave you underprepared for the paired Sprechen exam. See our guide to preparing for the Sprechen exam specifically for why that section needs its own dedicated practice, separate from general study hours.

Where this comes from: course-length figures are from Goethe-Institut’s online courses page for India and its course levels A1–C2 overview. The hour ranges in this article are our own calculation built from those published figures, not an official Goethe-Institut statistic.
