GMAT Private Tutoring | Quant, Verbal & Data Insights

From 107 £ /h

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.

About Me

I’m Bruno, founder of DG Prep, a physician and a private GMAT tutor with nearly two decades of experience teaching the exam.
My work is built around a straightforward principle: understanding an explanation is not the same as being able to solve an unfamiliar question independently, under time pressure. My job is to help you close that gap.
I take a diagnostic approach to preparation. Before recommending more practice, I examine how you read, reason, calculate and make decisions. A wrong answer might reflect a missing concept, an unsupported assumption or an inefficient approach. Different problems require different interventions—not simply more questions.
In our lessons, you will explain your thinking, compare methods and learn to recognise when an approach is no longer productive. I will challenge your assumptions, but I will also make sure you understand each step. You should leave knowing not only how a question works, but what to do differently when you encounter a similar challenge.
My teaching style is patient, direct and demanding in the right places. You do not need to arrive with an exceptional score. You do need a willingness to ask questions, examine mistakes honestly and practise between sessions. We build confidence through understanding and progress—not reassurance alone.
I work with students building their foundations, professionals returning to mathematics after several years, and experienced candidates trying to move beyond a score plateau. Preparation is tailored to your starting point, target and timeline, across Quantitative Reasoning, Verbal Reasoning and Data Insights.
I teach live online from Spain, primarily in English, with explanations in Spanish available when helpful. Alongside GMAT preparation, I have teaching experience in GRE Quantitative Reasoning and SAT Mathematics.
My objective is not to make you dependent on a tutor. It is to help you develop the reasoning, judgment and independence to perform without one.
Tell me what you are aiming for, what you have tried and where you feel stuck. That is where we begin.

I take care of evaluating each student with a series of 40 questions testing the basics in each area. Depending on the results, we will then be able to establish the strategy leading to the day of the test.

I am flexible both in terms of time and approach for each course. We can review course concepts, review difficult questions or practice some questions live. Live training allows me to give tips to students to save time on note taking or calculations.

Finally, we can do the whole course in English.

My results at the 6 GMAC mock tests were: 710 - 720 - 780 - 740 - 760 - 720.
Final result 720.

About me:

I teach the GMAT on a full-time basis and I have thousands of hours of experience teaching this test. I have become extremely proficient in teaching students of varying skill levels. My affinity for mathematics, love of logic, and passion for teaching make me an effective tutor that can help you reach your goals!

My Approach:
Here’s why working with me is better than enrolling in a course:
1. We can meet at times that are convenient for you
2. My lessons are fully tailored to student needs
3. I will help you build a customized study plan

This is what makes me unique amongst other tutors:
1. I have deliberately chosen standardized test instruction as my profession because I find it extremely rewarding to help my students learn, develop and reach their goals
2. I am committed to the success of my students from the moment they call me to when they gain acceptance to their top-choice program
3. A less experienced tutor may struggle to arrive at the correct answer whereas I will show you the best way to solve each problem
4. I do not waste your time with standard lessons; instead, my lessons are fully customized and are based on your individual weaknesses
5. I make worksheets for students who are struggling with basics concepts – there’s not enough practice material out there for people who need help with the basics

GMAT SPECIFICS:
LSAT: My love for logic and passion for teaching are what make me an excellent LSAT tutor. Many of my past students observed their largest gains in the logic games section of the LSAT particularly since I have an extremely well-structured approach logic games. With regards to arguments, I believe that a successful test taker should have a nuanced approach for each question type and this is precisely what I will help you do.

My Reviews:
I have numerous reviews on my tutoring profile. I have absolutely no control over the content of these reviews and they are completely authentic (as evidenced by the typos). I will happily send you a link. Here are some of my recent reviews:

“You always have the option to study alone, apply to a school alone with the information you collect over the forums and various resources. If you think you save money by doing that, you are wrong... Because as a professional and consultant myself, I recognize that certain skills, experience, and critical information cannot be gained right away. You need inside knowledge. I think Karim has that all. There will be times that you will say “huh, I didn’t know I can do that”. He helped me by avoiding to study to GMAT which in turn saved me months, and possibly countless frustrating hours. He helped me with choosing the right school and making the right decision. He helped me to get accepted. I mean, what else do you need? If you are thinking to hire him for GMAT or LSAT, do it. And hire him more for admission. An intent letter, resume, interview... Get it all, you will save time and money. Worth every penny. Real pro...” - Mehmet

“Working with Karim to prepare for the GMAT was one of the best tutoring experiences I've ever had. Not only does he provide his students with a wide variety of high-quality learning resources, but he also takes the time to understand your unique strengths and challenges in order to create a customized teaching approach and cater to your specific needs. He is clearly spoken, focused, patient, personable, incredibly encouraging, and really seems to know the GMAT exam inside and out. Karim shared many insightful study practices, as well as some great strategies for test day, which helped me achieve a score that was far above my initial goal. Even after my sessions with him had ended, he continued to follow up with me to ensure that I was confident and prepared for the exam, which was above and beyond what I could have asked of him. If you require any amount of help preparing for your exams - great or small - I highly recommend Karim's services.” - Liam

“Karim came prepared to our sessions and was able to help me through my specific problem areas, in both Quant and Verbal. He helped me improve my GMAT score by 100 points in three weeks. He was very helpful in directing me towards the most efficient and best use of the time I had. He was also great at explaining practice problems and concepts that I did not understand. Overall, I enjoyed working with Karim and felt that it was money well spent. Outside of his abilities as a tutor, he is also a really nice guy and cares about the success of his students. We have kept in touch even after I was admitted to a top-ranked business school. I couldn't have done it without him! Thank you, Karim!” - Jason

“Karim is an excellent GMAT tutor. I was struggling with the quantitative part of GMAT and decided it was time to look for a tutor. I searched online and spoke to different tutors, most of which were not very convincing. When I initially spoke on the phone with Karim, he was the only person who took the time to get to know me and understand my motivations for pursuing an MBA, as well as what exactly I was struggling with on the exam. We spoke for almost an hour and a half and not once did he mention price, or try to sell me on any of his services - unless I specifically wanted to talk about it. I was hesitant to sign up at first, but Karim was consistently genuine in his approach. Karim's Undergraduate degree in mathematics coupled with his MBA from Rotman (my dream school), qualify him to give me advice on the admissions process and to teach me the math concepts of the GMAT. I highly recommend Karim to anyone pursuing their MBA.” - Lucas

“I met Karim on almost 3 months ago and I have had an excellent experience. He is always on time, very organized and dedicated to his students' future. He comes in as a tutor but also as a coach working side by side with you towards your goals of MBA admissions. I totally recommend Karim to anyone interested in updating their Math and Reading Comp Skills as well as goal setting their MBA applications. Karim is a definite asset to anyone looking for a tutor.” - Aziz

Preparing for the SAT, GRE, or GMAT math sections and want to stop losing points on problems you actually know how to solve?
This course is built around one goal: getting you the highest possible score on test day, in the shortest time, with the least wasted effort.
I'm a State Engineer (IAV Hassan II) with a CPGE background in Mathematics and Physics — the most rigorous math preparation track in the Moroccan system. The math on these standardized tests is well within that level, which means I don't just know how to solve these problems — I know multiple ways to solve them, and I'll teach you the fastest and most reliable one for exam conditions.

What's covered — by exam:
1-SAT Math

- Heart of Algebra (linear equations, systems, inequalities)
- Problem Solving & Data Analysis (ratios, percentages, statistics)
- Passport to Advanced Math (quadratics, functions, polynomials)
- Additional Topics (geometry, trigonometry, complex numbers)
- Calculator vs. no-calculator strategy

2-GRE Quantitative Reasoning

- Arithmetic and number properties
- Algebra and coordinate geometry
- Data interpretation and statistics
- Quantitative comparison strategy
- Time management under pressure

3-GMAT Quantitative / Focus Edition

- Problem Solving and Data Sufficiency
- Data Insights section
- Elimination strategies for tricky wording
- Pacing and guessing strategy

My teaching approach:
Standardized math tests are not about being good at math — they're about recognizing patterns, avoiding traps, and managing time. I teach you both: the actual math and the test-taking strategy that separates a 650 from a 750 on the GRE, or a 680 from a 780 on the SAT.
Every session is personalized. We start with a diagnostic — I identify exactly which question types are costing you the most points — then we build sessions around fixing those specifically. No wasted time on things you already know.

Who this is for:

Students targeting top universities in the US, UK, or Europe (SAT)
Professionals applying to MBA or graduate programs (GMAT / GRE)
Anyone who feels "stuck" at a score plateau and needs a structured push
Students with strong school math who just need to learn the test format

What I offer:

Diagnostic session to assess your current level and target score gap
Personalized session plan based on your exam date and weak areas
Practice problems with detailed step-by-step breakdowns
Timed mock drills to build exam-day confidence
Available for intensive short-term prep (2–4 weeks) or longer structured programs

Hi, I'm Adam - an NYU Stern MBA graduate with a background in engineering and technology. I specialize in GMAT Focus Quant and look forward to helping you reach your target score.

If you're reading this, there's a good chance GMAT Quant is being a bit of a pain. Let's see if we can do something about that.

A bit about me - I scored a 780 on the classic GMAT (Q50/V47) and Q89 on the official GMAT Focus practice exam. So, I know what it takes to get an elite score. But, I began in the 600–650 range, and improving my score required a more methodical approach than simply learning more math. That's the approach I hope to share with my students.

One thing I've learned is that higher Quant scores are often driven by better execution, not just stronger content knowledge. During our sessions, we'll work on strategies that help you solve questions more efficiently, including:

* Pattern recognition to identify the fastest solution path
* Strategic use of answer choices
* Efficient approaches for common GMAT question types
* Time management and decision-making under pressure

I take a diagnosis-first approach. We'll identify what's holding your score back and build a focused plan with custom strategies around your specific needs, current strengths/weaknesses and schedule (yes - I know you might be working 50+ hours a week and we will work around it).

Our sessions will typically focus on:

* Targeted live problem solving
* Identifying recurring mistakes and bottlenecks
* Refining test-taking strategy
* Developing and adjusting your study plan

My goal is to keep lessons supportive, practical, and focused while also giving honest feedback and keeping you accountable to execution.

If that sounds like the kind of approach you're looking for, I'd be happy to see if we're a good fit.

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.
