About

I help ambitious applicants hit their target GMAT score and turn it into an offer from a top business school. I scored 715 on the GMAT Focus Edition (99th percentile), completed the MSc International Finance at HEC Paris with a 3.8/4.0 GPA, and studied Physics at UCL, so the Quantitative and Data Insights sections are where I add the most value. Since 2022 I have delivered more than 1,500 hours of one-to-one tuition in maths, economics and admissions tests, including the GMAT, TMUA, MAT, STEP and PAT. I have also helped applicants with their statements for HEC Paris and IE. Working with me is structured and transparent. We start with a diagnostic, agree a target score and test date, and follow a study plan built around your weakest areas. Each session mixes clear explanation, timed practice and review of every mistake, and you get written notes afterwards so you always know what to work on next. Outside tutoring I work in commodity trading in London, after roles in investment banking and consulting. That lets me help you link your preparation to your wider goals, whether that is an MBA, a Master's in Finance or a move into finance. I am a native Russian speaker and fluent in English, and I am happy to coach in either language.

Igor’s Executive Assessment Qualifications

The Executive Assessment tests the same quantitative, data and verbal reasoning as the GMAT, in a shorter format built for experienced professionals. I scored 715 on the GMAT Focus Edition (99th percentile), which shares its Quantitative Reasoning and Data Insights question types with the EA's Quantitative and Integrated Reasoning sections. I hold a BSc in Physics from UCL and an MSc in International Finance from HEC Paris (GPA 3.8/4.0), and since 2022 I have delivered more than 1,500 hours of one-to-one teaching, including GMAT and other admissions-test preparation. As the EA has no adaptive difficulty curve to manage in the same way, I focus on fast, reliable methods, careful timing across each section and a short, efficient study plan that fits around a busy working week. I also work in commodity trading in London, so I understand the time pressures of preparing alongside a full-time job.

Why do I coach?

I started tutoring in 2022 while studying Physics at UCL and found that I enjoyed it as much as the subject itself. Over 1,500 hours later, what keeps me coaching is the moment a student stops guessing and starts to see the structure behind a problem. The GMAT rewards exactly that. Most of the points people lose come from a handful of recurring traps and from poor timing, not from gaps in ability, and both can be fixed with the right method. I went through the same process myself on the way to HEC Paris, so I know how much a strong score can change the options in front of you, and how stressful the preparation can feel alongside a job or studies. I coach because I like being useful in a very concrete way: helping someone reach a score they were not sure they could get, and seeing it turn into an offer.
