This is the question everyone asks before starting — and the honest answer is: it depends. But "it depends" doesn't mean it can't be estimated. Here are the real session counts and the factors that decide whether you move fast or slow.
In Oui Academy's Speaking Curriculum, each level is broken into a set number of sessions, 60–75 minutes each:
| Level | Sessions | Running total |
|---|---|---|
| A1 | 12 sessions | 12 sessions |
| A2 | 13 sessions | 25 sessions |
| B1 | 13 sessions | 38 sessions |
| B2 | 13 sessions | 51 sessions |
That's roughly 51 sessions with a teacher to go from A1 through B2 — about 55–65 hours of direct class time. But that's only the time spent with a teacher; it's not the total real-world time you'll need to actually reach B2.
Class time is only one part of it. Your actual pace depends on:
A sustainable pace for most students: 1–2 sessions a week with a teacher, plus short daily practice. At that pace, A1 to B2 usually falls somewhere around 6–10 months, depending on the person. If you have a hard exam deadline (a study-abroad or immigration application, for example), talk to your teacher up front so the schedule can be worked backward from that date.
Take the 3-minute level check, or book a consult to build a schedule that matches your deadline.
