Math, calculus and physics can sometimes be overwhelming, especially when the theory or solving method is unclear. I am a cum laude Aerospace Engineering graduate from TU Delft and have helped other pupils with their problems since 2017. With my calm and stepwise explanation, a second alternative view of the solution procedure is given, which is often what is missing. I tutor a variety of math and physics courses on both secondary and high school levels, but also at a scientific bachelor level. These can either be theory/exercise-based, but also exam preparation.

Calculus I, the first course in this extensive mathematics curriculum, teaches students the foundational ideas of limits, derivatives, and how to apply them to real-world issues including rates of change and optimization. Calculus III, which builds on this basis, introduces partial derivatives, multiple integrals, and vector calculus, extending these concepts into several dimensions. When taken as a whole, these calculus courses build the solid analytical foundation and spatial thinking abilities needed for further study in applied mathematics, science, and engineering.

Students study Number Theory concurrently, exploring the complex patterns and characteristics of integers, such as primes, modular arithmetic, divisibility, and the classical theorems that form the basis of much of contemporary computer science and encryption. In addition to this theoretical emphasis, the Numerical Methods course gives students useful computational tools to help them approximate solutions to challenging mathematical problems that are impossible to solve analytically. Students are prepared for a variety of jobs in mathematics, engineering, technology, and other fields by this program, which blends strong theoretical knowledge with algorithmic problem-solving abilities.

I 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.

A practical engineering course designed to help you master mechanism simulation and mechanical system analysis using PTC Creo (formerly Pro/engineer).

Simulation has become an essential engineering tool for reducing development time, minimizing prototype costs, and improving design accuracy. However, many Creo users struggle to find structured training specifically focused on mechanism simulation. This course fills that critical gap by providing a hands-on, practice-driven approach to solving real engineering mechanism problems using Creo's Mechanism Design and Dynamics tools.

The course includes 55 carefully selected mechanism exercises covering a wide range of mechanical simulation topics. Each exercise is supported by detailed PDF explanations and more than 7 hours of guided video tutorials. In addition, 43 advanced practice tasks help reinforce learning and develop strong practical engineering skills. Some exercises also include alternative solutions to deep conceptual understanding.

A unique feature of this course is its simulation-based problem-solving methodology. Instead of relying solely on analytical equations, problems are solved through properly configured Creo Mechanism simulations. When correctly set up, the simulation results match the theoretical analytical results with (0%) zero-percent deviation, demonstrating the accuracy and reliability of the simulation approach.

Rather than focusing on heavy theory, this course emphasizes correct simulation setup, accurate input data, and practical engineering application. You will learn how to analyze motion, configure mechanisms properly, and obtain reliable engineering results through simulation.
The training includes multilingual support (English, French, Arabic), downloadable working files, and direct interaction with the instructor.
Whether you are an engineer, student, instructor, or Creo user seeking stronger simulation skills, this course provides a structured and practical path toward mastering Creo Mechanism simulation.

WHAT YOU WILL LEARN:
-> Build and simulate mechanical assemblies using Creo Mechanism tools.
-> Solve real engineering mechanism problems through accurate simulation setup.
-> Analyze motion, kinematics, and dynamics without relying on complex equations.
->Apply practical simulation techniques to real mechanical systems.
-> Interpret simulation outputs and validate engineering results.
-> Develop advanced hands-on skills through 55 structured mechanism exercises.
-> Improve engineering problem-solving through additional tasks and alternative solutions.
-> Configure simulations correctly to avoid inaccurate or misleading result.

My teaching approach follows a structured workflow:
define the problem → understand the requirements → analyze the constraints → develop the geometry or data structure → create the drawing, model, or spatial analysis → verify accuracy → refine the solution → communicate it clearly

I do not simply demonstrate isolated commands. I help you understand why a workflow is appropriate, how information should be structured, how accuracy can be verified, how alternative solutions can be evaluated, and how the final technical idea should be communicated professionally.

We can work with your course syllabus, engineering problem, technical drawing, CAD file, Revit/BIM model, 3D model, parametric definition, GIS dataset, map, design project, portfolio, graphic layout, or professional workflow challenge.

Whether you are learning your first CAD commands, solving an engineering problem, developing a BIM workflow, building a 3D or parametric model, conducting spatial analysis, or improving technical visual communication, I will adapt the sessions to your level, objectives, and pace.

My goal is to help you become an independent technical problem solver who can analyze, design, model, verify, visualize, and communicate solutions with confidence.

A practical engineering course designed to help you master mechanism simulation and mechanical system analysis using PTC Creo (formerly Pro/engineer).

Simulation has become an essential engineering tool for reducing development time, minimizing prototype costs, and improving design accuracy. However, many Creo users struggle to find structured training specifically focused on mechanism simulation. This course fills that critical gap by providing a hands-on, practice-driven approach to solving real engineering mechanism problems using Creo's Mechanism Design and Dynamics tools.

The course includes 55 carefully selected mechanism exercises covering a wide range of mechanical simulation topics. Each exercise is supported by detailed PDF explanations and more than 7 hours of guided video tutorials. In addition, 43 advanced practice tasks help reinforce learning and develop strong practical engineering skills. Some exercises also include alternative solutions to deep conceptual understanding.

A unique feature of this course is its simulation-based problem-solving methodology. Instead of relying solely on analytical equations, problems are solved through properly configured Creo Mechanism simulations. When correctly set up, the simulation results match the theoretical analytical results with (0%) zero-percent deviation, demonstrating the accuracy and reliability of the simulation approach.

Rather than focusing on heavy theory, this course emphasizes correct simulation setup, accurate input data, and practical engineering application. You will learn how to analyze motion, configure mechanisms properly, and obtain reliable engineering results through simulation.
The training includes multilingual support (English, French, Arabic), downloadable working files, and direct interaction with the instructor.
Whether you are an engineer, student, instructor, or Creo user seeking stronger simulation skills, this course provides a structured and practical path toward mastering Creo Mechanism simulation.

WHAT YOU WILL LEARN:
-> Build and simulate mechanical assemblies using Creo Mechanism tools.
-> Solve real engineering mechanism problems through accurate simulation setup.
-> Analyze motion, kinematics, and dynamics without relying on complex equations.
->Apply practical simulation techniques to real mechanical systems.
-> Interpret simulation outputs and validate engineering results.
-> Develop advanced hands-on skills through 55 structured mechanism exercises.
-> Improve engineering problem-solving through additional tasks and alternative solutions.
-> Configure simulations correctly to avoid inaccurate or misleading result.
