You stop when you have to speak
Maybe you read and write in English every day. Maybe you don't. But when you have to speak, your brain stops. You translate every word in your head first, and then the panic arrives before the sentence does.
You have been at B2 for years
You got your B2 a long time ago. You still get the same score in practice tests that you got two years ago, and you don't know why you stopped moving.
You don't know where to start
You have books, PDFs and free videos. You open them, you feel behind, and you close them again. Nobody has told you what to do first, or what to do next.
Nobody tells you why it is wrong
You see the right answer, but never the reason. So you make the same mistake next month, and the month after that, and your score stays where it is.
What happens if you don't pass in the next 12 months?
Studying with nothing to tell you what to do next.
Roles advertised online for managers and professionals ask for English.
On your speaking and your writing, the two skills you actually use at work.
Roughly what it costs to sit the exam twice and not pass either time.
The exam fee is the small cost. The job you don't apply for is the big one.

Find the problem first. Then fix it, in order.
Most C1 courses give you a library and wish you luck. Here, before you study anything, we find out where you are losing marks. Then you get a plan with a date, and one priority at a time, so on a bad day you still know what to do.
Find your real level
You do one full practice test. Not in three weeks, now. Then we both know which paper is taking your marks, and you can stop guessing.
Same student, same day. Writing and Speaking are already above C1. Use of English and Listening are not. Without this picture she would study everything, and everything is the slowest way.
Make your six-month plan
Your test results become a plan with a date. One priority at a time, built around the hours you really have, not the hours you wish you had.
The goal is 70%
Trying to get 100% is how people spend a year studying and never speak. Aim for 70% and use the language now.
Be a detective
Every mark and every mistake goes in your error log. Then you study what the log tells you to study, not what you feel like studying. Your weak points get smaller because you can see them.
Learn how to play the exam game
How each paper is marked, how to use your time, and what to do when a question is hard. This is how a good level turns into a good mark.

What students say
In their own words. Some of them had already failed once before they found me.
The call is your starting point
I look at your level, your exam date and what has gone wrong before, and I tell you if you are ready to start preparing for this exam or not.
I don't accept everybody inside the programme, because we both need to be honest with each other. If the course is not right for you, you lose money. And if you are not right for the course, the other students are affected too.

The price of the Accelerator and VIP depends on your level, your exam date and how much support you need.

I know what it feels like to have a language stuck inside your head
I moved to Spain with a degree in Spanish and Portuguese from one of the best universities in the country, and I still didn't feel confident when I opened my mouth. There were four different days in those first months when I came home and cried after meeting new people, because a whole evening in Spanish left me overwhelmed and frustrated. People asked my friends if I was mute.
The degree didn't make me ready. Living it did.
I am so glad I trusted my instincts, ignored my fears and moved anyway. Eight years of living in Spain later, I have a level of Spanish that I am so fu**ing proud of. Not because I am talented, and not quickly. I kept going when it was hard, and I kept going on the days when I didn't want to.
Six and a half years ago I was teaching from the floor of my bedroom, after I lost my job at the start of the pandemic. Ten years and around 4,000 students later, everything I learned about why good English still gives a low mark is inside this programme.
Where you are today is temporary. Keep taking small steps and you will get there.
