Getting in touch with Stefan was the best thing that ever happened to me. He's dedicated and passionate about what he does, he zeroes in on the parts you're weaker at while also sharpening the parts you're already good at. The prep is challenging but it's absolutely worth it. I'd rate him 10/10!

Frequently asked questions

1. What does your TOEFL prep program look like?
The program is organized to prepare you for all four parts of the TOEFL test: Academic Reading, Academic Listening, Academic Speaking, Academic Writing.

Every program consists of individual 60-minute lessons and full TOEFL test simulations that run about 3h on average. Our lessons are entirely online, 1-on-1 with expert professors who specialize in the TOEFL. After every lesson, you get a progress report, homework, and a plan for the next session.

As part of the program you also get exclusive access to individual workshops and consultations on applications to elite universities and scholarships, as well as advanced workshops on academic writing and scientific work in English.
2. How long does TOEFL prep take?
We tailor every program to the student — duration, special features, and instructor choice (native or bilingual) are set based on your level, goals, and prior experience.

Programs run from 3 to 6 months depending on the goal. After a free consultation we recommend the program with the best odds of getting you to your target score.

Between lessons you'll need to put in about an hour or two on homework. We offer 30+ slots per week, including weekends and evenings.
3. What do the TOEFL test simulations look like?
Our simulations are designed to give you a feel for what taking the TOEFL live is like. You'll face the same pressure, the same time limits, the same amount and difficulty of tasks, and at the end, an expert analysis of your result from our three-person review panel.

Our simulations are extremely accurate. The deviation from the final results is under 5%, which means that if you score 100 points on our simulation, you'll score between 98-103 points on the real test. After every simulation you get a detailed breakdown of your results with recommendations for improvement.
4. What results can I expect after the program?
Our students' average TOEFL score over the past 4 years is 102 points. Of those, 95% of students pass with the required score for their chosen university on the first attempt, while 78% enroll at one of the top 100 universities in the world.
5. Which universities do your students enroll at after TOEFL prep?
Our alumni most often enroll at top European universities that accept the TOEFL iBT score:

Italy:Politecnico di Milano, Università Bocconi, Università di Milano, Università di Padova, Università di Bologna, Università Iuav di Venezia, Ca' Foscari, La Sapienza, LUISS, Politecnico di Torino.
Germany: TU München, LMU München, Heidelberg, RWTH Aachen, Humboldt and Freie Universität Berlin, KIT Karlsruhe, Tübingen, Freiburg.

Beyond Europe, our alumni also enroll in the US (Harvard, MIT, Stanford, Cornell, NYU, UNC, UCLA, Carnegie Mellon) and Canada(University of Toronto, McGill, UBC, Waterloo, Queen's). If you're targeting a TOP 100 university, chances are one of our alumni is already there.
6. How does your guarantee work?
If you don't hit your target result, you get an extra month of instruction free of charge, at least 8 additional lessons and one test simulation. Over the years, on average fewer than 2% of students have ever used this guarantee because, fortunately, they didn't need to.
7. Does a high TOEFL score really increase your chances at scholarships and admission to prestigious universities?
Absolutely! Research shows a direct correlation between high TOEFL results (100+ points) and successful admission to prestigious universities. Scholarships are even more selective. The data shows that students with 110+ points on average have higher odds of winning a scholarship.
8. Who are your professors?
All our professors have a minimum of 5 years of experience preparing students for academic tests and a proven track record with dozens of students. Each of our professors has also completed detailed, thorough training with our founders and maintains an average score of over 100+ across their careers with their candidates. Our founder Stefan Mrvaljević is a recipient of the Chevening Scholarship (UCL) and the Swedish Institute Scholarship (Lund University), and is directly involved in your academic journey, from TOEFL prep to successful university admission and beyond.
9. Who are your ideal students?
