have graduated with a degree in chemical engineering from the University of Edinburgh, UK. I am also an Erasmus Mundus scholar with a master's in Analytical Chemistry from Uppsala University. Currently, I am pursuing a PhD in physical chemistry.

I have been tutoring since 2012 to fund my education expenses. I formally began tutoring in 2014 as part of my vocational training as a teacher in Ghana, funded by the University of Edinburgh. The formal training has taught me a lot about curriculum development, time management, and fusing my teaching methodology to my students’ needs. I have been tutoring in Physics, Chemistry, and Math, in person and online; the hybrid model has allowed me to reach out and teach students in 8 different countries. I have successful students from these past nine years who have not only commended my work ethic but can also stand testament to my enthusiasm.

My excellent academic career has nurtured in me a natural talent for teaching. My experiences have taught me how to tackle one problem at a time, and I believe that using this approach—paired with my unconventional examples that force students to think outside the box—I can truly provide an excellent understanding and explanation. My teaching methodology is based on two main things: skill development and adaptation. Initially, I create a skeleton of the most suitable methodology tailored to the preferred curriculum, after which, I adapt that lecture to the specific needs of the student based on their knowledge and grasp of the concepts. Second, I like to develop analytical and scientific ability along with knowledge in my students, and for that, I use a combination of resources in the form of worksheets, class tasks, and past papers. Last, I believe in the strong ethic of providing feedback to the parents, so that they are aware of their child’s progress.

Frequently Asked Questions:
Which subject(s) do you teach?
I teach math, mechanics, statistics, chemistry and physics. I also teach biology up to GCSE level.

When are you available? My timetable is quite flexible. I am happy to work weekdays, week evening and weekends.

Which ages and levels do you teach? The majority of my students are between the ages of 10-18, but I also teach college Students. I am also helping foundation and first year university students.

Which qualifications do you prepare your students for? GCSE, o-level, A/S-level, A-level, IB, School entrance exams and SATs

Describe your arrangements for online tutoring? I use Zoom online sessions since it has many tools and features specially designed for interactive and visual learning. I am fully equipped with modern gadgets for e-learning. I use Google drive and docs to share files.

Hi there
My name is René. I combine sound academic expertise in chemistry and biochemistry with over 10 years of teaching experience (more than 5 of which were successfully online). I already hold a Bachelor's degree in Food Technology (grade 1.7) and am currently completing my second Bachelor's degree in Chemical Biology at TU Dortmund (grade 1.8), after which I will immediately begin my Master's degree in Chemistry.

My primary focus is on organic chemistry, particularly organic natural product synthesis, retrosynthesis, organic catalysis, and organometallic chemistry. My bachelor's thesis at TU Dortmund was on the topic of "Synthesis of a substituted 2,3-dihydrofuro[2,3-b]tropone as a model compound in studies on the total synthesis of marine tetraterpenoids of the gukulenin family." To further my scientific expertise, I am currently taking four specialized master's modules at Ruhr University Bochum with Prof. Gerald Dyker: Stoichiometric Organometallics, Catalytic Organometallics, Designing Organic Syntheses, and Competing Reactions. In addition, I have excellent grades in physical chemistry (1.3 in PC 1 & 2 and 1.7 in quantum mechanics/PC 3) and a strong foundation in biochemistry.

In my teaching, I emphasize a deep, logical understanding rather than rote memorization: I explain organic reactions from the ground up using molecular principles such as MO theory, the HSAB principle, quantum mechanics, and pKa values. I place particular emphasis on the precise distinction between thermodynamics and kinetics – for example, when differentiating between basicity and nucleophilicity – in order to make reaction pathways such as nucleophilic substitutions or eliminations predictable.

Over the past 10 years, I have successfully guided numerous students of chemistry, biochemistry, medicine, pharmacy, and engineering through their most challenging exams. My students regularly achieve top marks in written and oral exams, and I am happy to provide feedback and references upon request. Whether you need preparation for demanding university exams or advanced study at the master's level, please feel free to contact me so we can easily arrange an initial consultation.
