Knowing how to solve a question and solving it reliably under time pressure are different skills. We work on both. I’m Bruno, a physician, GMAT tutor and founder of DG Prep, with approximately 19 years of experience teaching the exam. I work with MBA and business master’s applicants who want individual preparation, clear priorities and a deeper understanding of how to approach unfamiliar questions. We start with your performance: not a generic syllabus. Your current score, target, deadline and approach to questions guide our work. We distinguish gaps in knowledge from difficulties with reading, reasoning, calculation, timing and decision-making. Understanding why you make an error is the starting point for correcting it. Quantitative Reasoning: Strengthen arithmetic and algebra, translate word problems accurately, compare solution methods and develop efficient, reliable calculations. Verbal Reasoning: Build precise Reading Comprehension and Critical Reasoning skills. Learn to identify conclusions, test assumptions, distinguish evidence from inference and explain why an attractive answer is still wrong. Data Insights: Work on Data Sufficiency, Table Analysis, Graphics Interpretation, Multi-Source Reasoning and Two-Part Analysis, with particular attention to identifying relevant information and managing time. You participate actively in every lesson. You explain your reasoning, test your assumptions and compare approaches. Rather than simply watching me solve questions, you learn how to choose and execute a method yourself. We strengthen the underlying concepts while developing the judgment needed to apply them under exam conditions. Between sessions, you receive targeted practice and clear priorities for independent study. We revisit recurring errors and adjust the plan as your performance develops. This preparation is suitable whether you are building your foundations, returning to the exam after a break or trying to move beyond a score plateau. Lessons are delivered live online from Spain, primarily in English. Explanations in Spanish are also available when helpful. Sessions booked through this listing are taught by me personally. I recommend lessons according to your needs and progress—not a predetermined number of hours. My objective is to help you become a more capable, independent test-taker. To get started, send me a message through Apprentus with your target score, planned exam date and latest practice-test results, if available. Tell me what you currently find most difficult, and we can identify the right starting point. Please use a laptop or desktop computer with a stable internet connection, and have pen and paper available. Before our first lesson, share your target score, planned exam date and latest practice-test score with section breakdown, if available. Include two or three questions that illustrate your main difficulties. New to the GMAT? Share your target programme and preparation timeline instead.

My lessons are designed to deliver clear progress from the very first session. I quickly identify gaps in understanding and focus on strengthening core concepts before building up to exam-level questions. Students are guided step by step until they can solve problems independently and confidently. Each lesson is structured but flexible: we revise key theory, practise targeted questions, and regularly use past papers to prepare for real exam conditions. This approach consistently improves both understanding and exam performance. Lessons last 60 minutes as standard, with longer sessions available during exam periods or when intensive preparation is needed. I teach GCSE, A-Level, entrance exams, and GMAT, supporting students of all abilities — whether they need to build foundations, improve grades, or aim for top results. My goal ismeasurable improvement in confidence, accuracy, and exam success.

I offer mathematics courses that support students at every stage of their academic journey. Each program is designed to build confidence, sharpen logical thinking, and provide the clarity needed for success in school, exams, and future study. Secondary Level — strong foundations in algebra, geometry, data, and reasoning for students in Grades 6–9. High School Level — advanced study in algebra, functions, trigonometry, and higher-level mathematical thinking for Grades 10–12. University Level — academic support in calculus, analysis, linear algebra, statistics, and proof-based mathematics. International Exams — specialist preparation for SAT, GCSE, and A-Level.
