GMAT Tutors : 1-1 GMAT Preparation

I am a highly motivated and results-driven individual with a strong academic background in health and education. Having achieved outstanding results in Medicine Interview preparation, IELTS, TOEFL, and GCSE, I bring both academic excellence and practical experience to my work. I have successfully helped students secure offers from top medical schools such as Bristol and UCL, and have coached candidates through Oxford mock interviews and Imperial MMIs with a 95% success rate.

My teaching philosophy centres on empowering students to think critically, communicate effectively, and perform confidently under pressure. I take pride in creating a supportive, engaging, and personalised learning environment that builds not only knowledge but also self-belief. I continuously refine my methods based on student feedback and current admissions trends to ensure my guidance remains relevant and impactful.

I am passionate about education as a tool for transformation and dedicated to helping every learner achieve their fullest potential with confidence and clarity.

I’m a full-time private tutor with an extensive background in maths and data tech. I’ve been tutoring/taught for over twelve years, and worked in the data tech industry for six years. My academic background is from Sussex University. I completed my MMath degree with a 1st class honours in 2014 writing my dissertation on Bochner-Riesz summability and Strichartz estimates. I then completed my PhD in maths in 2019 under the Hirschfeld scholarship passing with minor corrections (2019); my thesis was titled “Topics in Geometric and Harmonic Analysis on Symmetric Spaces and Lie Groups”. I started tutoring as an A-level assistant at school helping GCSE students with maths work in the classroom. I picked it up again as a university undergraduate as a convenient way to fund my studies. I quickly realised that I had a knack for tutoring being able to get the best out of my students and consequently help them achieve their goals. Tutoring has since become my passion. From that point, I’ve had a range of tutoring positions including acting as a classroom assistant in a local school, one-on-one tutoring online and in person, leading university workshops, marking homework, being a university examiner, delivering lectures at universities, and leading technical training in industry. My PhD further enhanced my tutoring. I had regular contact with my research supervisor who had a remarkable ability to explain complex maths concepts in a simplified way unfolding the concepts as if he was telling a story. I integrated this into my tutoring technique. I constantly strive to develop this skill further and pass it onto my students to engender their enthusiasm. I entered the workforce following the completion of my PhD as a data specialist working in tech and applying maths to solve machine learning problems. An example was acting as an intermediary translating academic mathematical models into Python and PySpark code to improve the computation of aggregate functions. I continued teaching responsibilities being responsible for training work colleagues in data engineering skills and advanced machine learning. I’m now a full time tutor after spending six years in data tech. I have expanded my tutoring portfolio into further areas including: computer science, data engineering/science best practices, dissertation advice, maths entrance exams, mechanics, university application assistance, Python/SQL pair programming, statistics, and test preparation.

Dr Clement Twumasi is a Senior Medical Statistician at the University of Oxford (Nuffield Department of Medicine) and a Royal Statistical Society Chartered Statistician (CStat). He is an experienced statistical consultant with an outstanding international academic and teaching record.

Dr Twumasi previously worked as a Clinical Trials Statistician at Imperial College London and held a postdoctoral position in Biostatistics at the University of Oxford’s Department of Statistics. He earned his PhD in Mathematics from Cardiff University in 2021 as a Vice-Chancellor’s PhD Scholar, specialising in mathematical and stochastic modelling of biological systems. He also completed an MPhil in Statistics at the University of Ghana with a perfect GPA (4.0/4.0), and his master’s thesis was awarded Best Mathematics Research in Ghana (2018) across all universities. I have an accredited teaching fellowship with Advance Higher Education (HE) in the UK, demonstrating my teaching competence.

He serves as an academic reviewer for leading Q1, high-impact journals, including PLOS One, PLOS Computational Biology, the International Journal of Forecasting and other Springer Nature Q1 journals (including Discover Artificial Intelligence & Scientific Reports journals), reviewing work on advanced time-series modelling, machine learning, infectious disease modelling and mathematical biology.

Alongside his research career, Dr Twumasi is a passionate and highly effective educator. He has extensive experience delivering 1-to-1 online tutoring in mathematics and statistics at all levels, including university and postgraduate study, through one of the UK’s leading tutoring providers, The Profs Tutors. He also teaches R programming and advanced statistical methods on his YouTube channel, “Clement Twumasi Educative Channel” with over 25K+ subscribers. He has also supported students preparing for professional and admissions exams such as the SAT, ACT, GMAT, and GRE (Mathematics) over the years. In addition, he has guided many students through university-entry applications, particularly for postgraduate programmes, including Master’s and PhD applications, both within and outside the UK.

Dr Twumasi has successfully mentored and supported many students in gaining admission to top universities in the UK and internationally. He is known for his clear explanations, structured teaching approach, and ability to make complex statistical concepts accessible and practical.

He offers expert tutoring and academic support in:

i) Mathematics and Statistics (undergraduate to PhD level);

ii) Biostatistics and Medical Statistics;

iii) Statistical programming (R, Python, SPSS, STATA, etc.);

iv) Research methods, data analysis, and thesis support;

v) Exam preparation, coursework, and dissertation guidance.

If you are seeking rigorous, supportive, and results-driven tutoring from an Oxford-based mathematical statistician with real-world research, teaching, and statistical consultancy experiences, Dr Twumasi provides a truly exceptional learning experience.

I can be flexible with scheduling meeting times, and can adjust to suit the expectations and specific needs of my clients.

I am currently pursuing a PhD in Mathematics at the University of Cambridge. I hold both bachelor’s and master’s degrees in Mathematics from IIT, one of India’s top institutions. With over 4 years of teaching experience and more than 300 students taught globally, I bring both depth and clarity to my lessons. I am well-versed with UK curricula including GCSE, IGCSE, A-levels, IB, and university-level mathematics. My teaching is tailored to each student’s needs, helping them build strong foundations and achieve top grades with confidence. My lessons focus on deep conceptual clarity, ensuring students truly understand the subject and can tackle even advanced problems with confidence. I also share powerful tips and exam strategies. With my strong subject knowledge and friendly, adaptive teaching style, I help students not just learn—but excel.

I have 30+ years of experience in tutoring in parallel to my career as an engineer and a business consultant. As I am not traveling anymore, I can use these assets to help students in both tutoring and making assignments from a distance besides my consulting work. I am based in Brussels.
Most of my students come to me from word of mouth since my hit rate is quite high: they get quite quickly autonomous, needing much fewer sessions than with a purely academic tutor. My explanations are always based on daily life applications, as I have been using most topics in my professional career (I started as a basic nuclear engineer).
For Business Studies, I also use my broad experience as a business consultant: I still coach and train Engineers into Business & Sales engineers with a few Scandinavian technical companies since 1995.
