If you’re wondering how many Spanish classes it takes before the language starts to feel like yours, we can answer that with our own records rather than a guess. We went back through 1,896 one-to-one classes taught since 2020, to 67 adult students, and counted what actually happened.

Here’s the part that surprised us most: the decision is made much earlier than anyone expects. Not at month six, when the grammar gets hard. In the first two or three weeks.

13% of students never come back for a second class

Nine of our 67 students took one class and stopped. That’s the single biggest drop anywhere in the data, and it happens before anybody has learned much of anything.

After that, the picture changes completely. Of the students who book a second class, 94.8% book a third. From there the rate stays above 90% at almost every step. So the question isn’t really “will I stick with Spanish for a year.” It’s “will I come back once.”

We can’t tell you why the nine stopped. Our booking system records classes, not reasons, and we’re not going to invent a story about motivation to fill that gap. What we can see is when it happens, and it happens immediately.

What happens if you make it to class five

71.6% of our students reach a fifth class. Of those, 77.1% go on to ten or more, and 22.9% pass fifty classes.

That’s the number we’d want to know if we were the one deciding whether to book. Getting to five classes isn’t a small milestone that leads to a slightly better chance. It’s most of the battle. Past it, people behave like people with a habit instead of people trying something out.

How long do people actually stay?

Among students who reach ten classes, the median relationship with us lasts 512 days. That’s about 17 months. The average is longer, 629 days, pulled up by students who started in 2020 and are still here. Our longest-running student has taken 289 classes.

Seventeen months is not what the ads promise. Language apps sell 30-day challenges, and a challenge is a nice way to start, but it isn’t how an adult gets comfortable speaking. The students who get there are rarely the intense ones. They’re the ones who kept a weekly slot through two vacations and a busy season at work.

A number worth being honest about

Cambridge English publishes the hours usually associated with each level: roughly 180 to 200 guided hours to reach A2, and 350 to 400 to reach B1. Our committed students take a median of 33 classes, at a median pace of about 29 classes a year.

Do that math and class time alone would take well over a decade to reach B1. We’re telling you that because it’s true, and because it points at the thing that actually decides how fast you progress: what you do in the other 167 hours of the week. An hour with a teacher is where you find out what’s broken and how to fix it. The repair work happens between classes, in podcasts, messages, mistakes with your in-laws, and the five minutes you spend rereading your notes.

That’s also why we plan classes around what you’ll do next, not just what we covered today.

What this changed about how we teach the first month

Once we saw where the cliff was, we rebuilt the beginning. Three things changed:

• You leave the first class with something you can actually say to a real person that week, not with a tour of the grammar you’ll meet later.
• The fifth class is a checkpoint. We look back at class one together, because progress at this stage is real and almost impossible to feel from the inside.
• The free consultation comes before you pay anything. Of the 70 people who booked one, 40 went on to take classes, and the conversations that didn’t lead anywhere usually surfaced a mismatch we were both glad to find early.

So what should you take from this?

If you’re deciding whether to start: the risk you’re weighing isn’t a year of your life. It’s whether you book a second class. Plan for five, and judge it then.

If you’re already learning and it feels slow: 17 months is the normal shape of this, not a sign you’re behind. Consistency is doing more for you than intensity would.
