When I was a young child, I believed I was not a mathematical person.

It wasn't until I met an amazing teacher at age 15 that I discovered my mathematical genius and my life was changed forever.

I'm eternally grateful to that teacher.

My teacher knew that self-image and self-belief is the key to unlocking your child's mathematical abilities.

Everyone is good at maths, but we all have different styles of thinking.

Bad teachers teach every child the same way.

My job is to find your child's style of mathematics and allow him to discover that for himself.

When he discovers that, he will begin to enjoy the beauty and power of mathematics

...and then you will see as the grades begin to soar.

As a dedicated tutor with extensive experience in preparing students for standardized exams such as the SAT, GMAT, and SSAT, I understand the unique challenges that each of these tests presents. My approach is comprehensive and focuses on building a strong foundation in critical areas such as Mathematics, Quantitative Reasoning, Verbal Skills, and Analytical Writing. Each program I develop is tailored to the specific requirements of the exam, ensuring that students are well-prepared and confident on test day.

Having a deep understanding of the test formats and question types allows me to provide personalized strategies that target each student's individual strengths and weaknesses. I believe that every student has a unique learning style, and my goal is to enhance their test-taking skills while improving their time management. By fostering a supportive learning environment, I aim to boost students' confidence and empower them to achieve top scores.

My tutoring sessions incorporate a variety of effective methods, including real exam questions and timed practice tests. This hands-on approach allows students to familiarize themselves with the types of questions they will encounter, making the actual exam feel less daunting. I teach proven techniques for tackling even the most challenging problems, ensuring that students feel equipped to handle any question that comes their way.

One of the key components of my tutoring is helping students develop effective study habits. I provide guidance on creating a structured study plan that maximizes their preparation time and aligns with their personal goals. This structured approach not only keeps students on track but also helps them build a sense of accountability, which is crucial for success.

In addition to academic preparation, I also focus on the psychological aspects of test-taking. Many students experience anxiety leading up to exams, which can affect their performance. I teach relaxation techniques and mental strategies to help manage stress, allowing students to approach their exams with a calm and focused mindset. By addressing both the academic and emotional challenges of test preparation, I equip students with a well-rounded toolkit for success.

Feedback is an essential part of the learning process, and I make it a priority to provide constructive and actionable insights during our sessions. After each practice test, I conduct a thorough review of the results, highlighting areas for improvement while also acknowledging progress. This continuous feedback loop helps students understand their growth and keeps them motivated throughout their preparation.

My commitment to student success goes beyond just teaching content. I aim to inspire a love for learning and self-improvement in each of my students. Many of my former students have gone on to achieve their academic goals, securing places at prestigious universities and programs. Their success stories are a testament to the effectiveness of my tailored approach and the dedication I bring to each tutoring session.

If you're looking to master the SAT, GMAT, or SSAT with confidence, I invite you to book a session now. Together, we will develop a customized learning plan that suits your individual needs, ensuring that you are not only prepared to face the test but also equipped to excel and reach your highest potential. With my guidance and your commitment, we can achieve outstanding results. Let’s embark on this journey to success together!

Extensive experience in preparing exams for high school and first semesters of university. It is important to fix the basic concepts in order to understand slightly more complex problems. This must be done with a lot of patience and clear examples from real life, which is where physics has been observed and studied since its inception. I propose some classes with clear objectives, obvious examples from day to day and periodic monitoring of the results. cheer up.
