Hi there! My name is Konstantinos, but you can call me Tino. I’ve been tutoring for almost 17 years, starting when I was just 12. I have experience in a wide range of subjects, including Elementary, Middle School, and High School Math, Pre-Algebra, Algebra I and II, College Algebra, Geometry, Pre-Calculus, Calculus, Statistics and Probability, SAT Math Preparation, as well as Biology, Chemistry, Economics, and Business. I’ve worked with AP, IB, and college students, helping them improve their grades from Ds and Cs to Bs and As. My goal is to guide students and help them achieve their full potential. If you have any questions, feel free to ask!

I’m moving to Toulouse, France, to pursue a PhD in Economics at the Toulouse School of Economics. Currently, I’m based in Barcelona, where I completed my Master’s in Economics at the Barcelona School of Economics. In 2022, I earned a Master’s in Data Sciences from ESSEC Business School and CentraleSupélec Engineering School in Paris, France. My bachelor’s degree is in Business Administration from Emory University in Atlanta, GA, USA. My dream is to work in research in development economics. Tutoring has always been a passion of mine, as I love helping people achieve their goals. I’m available for both in-person and online tutoring and have extensive experience with both.

TRANSFORMING LEANERS INTO TOP ACHIEVERS— FROM PRIMARY TO IB

Welcome to a learning experience designed to inspire confidence, mastery, and academic excellence across Mathematics, Science, Physics, Chemistry, and Biology. Whether your child is building foundational understanding in primary school, preparing for the challenges of IGCSE/MYP, or tackling the rigor of A Level and IB (HL & SL), my classes are structured to deliver real, measurable progress.


WHY LEARN WITH ME?

I bring over 10 years of professional tutoring experience** backed by a strong academic foundation. Having graduated with honors from both the Faculty of Science and the Faculty of Medicine, and further trained in advanced mathematical and scientific pedagogy at top institutions like MIT, I have developed a teaching approach that blends expertise, empathy, and innovation.

BUT MY PASSION FOR TEACHING COMES FROM A DEPPER PLACE.

As someone who once struggled with dyslexia and ADHD, finishing at the bottom of the class, I personally understand the frustrations many learners face. With the guidance of a mentor, I transformed my academic life—rising to the top 1% worldwide in SATs and earning placements at prestigious universities.
This journey fuels my mission: to help every student unlock their potential, no matter where they begin.


WHAT I OFFER

My classes are designed for both students who need patient, structured support and high achievers seeking challenge and enrichment.

* Support with homework, revision, coursework, and past papers


FOR PARENTS

Your child will be learning in a supportive, structured environment designed to strengthen skills, fill gaps from earlier years, and rebuild confidence.
You can expect:

* Steady performance improvement
* Clear progress tracking
* Regular feedback
* A tutor who treats your child’s success as a shared mission

FOR STUDENTS

You deserve a teacher who understands you.
You deserve lessons that make difficult concepts finally make sense.
You deserve a guide who will help you go from confused to confident—and even exceptional.
I’m here to help you build the skills, habits, and mindset that top-performing students rely on.

SEE WHAT OTHER PARENTS AND STUDENTS SAY

I always encourage new clients to read my reviews as they reflect the real results, growth, and transformations that students experience in my sessions. Your trust matters and my past students’ success stories say more than I ever could.


LET'S BEGIN THE JOURNEY TOGETHER

Whether you’re looking to catch up, keep up, or excel, I’m here to help you achieve your goals with patience, passion, and proven techniques.

I am a qualified engineer from Arts et Métiers ParisTech and followed a preparatory class, accumulating more than 10 years of experience as a private mathematics teacher. My goal is to help your child reach their full academic potential in mathematics and develop skills that will prepare them for a bright future.

Why choose my courses?

Would you like your child to:

Significantly improve your results in mathematics/physics-chemistry?
Join a selective curriculum?
Become independent and confident in your abilities?
Over the last 5 years, I have had the privilege of supporting more than 30 French students, from middle school (sixth, fifth, fourth, third) to high school (second, first, terminale), towards academic success. My students obtained good averages, passed the certificate, the baccalaureate and the preparatory classes, while strengthening their self-confidence.

My teaching method in 3 steps:

Short term: Immediate improvement in average by assimilating the course and preparing for assessments. This includes assimilating the course, taking notes, practicing standard exercises, anticipating teachers' expectations and test questions, as well as acquiring writing methods.

Medium term: Integration of reasoning and working methods. Your child will learn to work regularly in this order: assimilation, training exercises, preparation for assessments and analysis of results.

Long term: Establishing clear goals, building the steps to achieve them, realizing the SIMPLICITY of mathematics, building confidence in your abilities and unlocking your child's potential.

Details of the formula:

One to two sessions of 1h30/2h per week to assimilate the course and prepare for the evaluations.
Classes delivered via Google Meet for effective online learning.
Use of a virtual whiteboard to facilitate the assimilation of concepts.
Access to an online library including 10 mathematics reference books.
Over 1000 online exercises to strengthen math skills.
Questions ?

Contact me now on Apprentus, and I will respond quickly. Together, we can give your child the future they deserve through an exceptional math education.

Don't let this opportunity pass you by! Book today for outstanding results in mathematics.

About Me

Born in London to French and American parents, I grew up between the three countries and now live in Barcelona. In addition to teaching, I also run my own business as a football agent.

Lessons

As a friendly tutor that will make lessons fun for you, I want to empower you to achieve your goals! I am able to match the needs of my students depending on their ability level and age. Ranging from five to seventy five, my students appreciate my individualised approach to their learning and my constant attention to their well being and detail. I try to make lessons fun so that you can be empowered to achieve your best results possible!

Qualifications

After completing a Political Science degree with a focus in International Relations and Spanish at UCLA, I finished, with merit, a postgraduate business degree (MBA) at the University of Liverpool. In addition, I am a certified high school mathematics teacher in the United States with experience teaching subjects such as Algebra I, Algebra II, and test preparation. I taught high school math for multiple years in East LA with the program Teach for America that places top university graduates in under served neighbourhoods. As I lived in the UK for many years and have taught many British students, I am also intimately familiar with the UK curriculum. Furthermore, I have tutored students studying the International Baccalaureate (IB) curriculum for many years. Lastly, I have a TEFL credential, which has allowed me to teach English to dozens of students.
