Need help with math and science (physics, chemistry, etc.)? As a 33-year-old civil engineer, I'm happy to help! I'll learn at your own pace, using plenty of examples to illustrate the material. I have years of experience teaching both simple and complex subjects.

The lessons run as follows. First of all, together we look for the student's biggest stumbling blocks. These can be related to the subject matter as well as to the study method. From there, I continue to work at the pace of the student and encourage them to ask as many questions as possible. I also give them tips and tricks, and improve their working methods where necessary. During the lesson I give many examples to make the subject matter more interesting and we solve exercises together. Once the student has mastered the exercises from the lesson, I give some more challenging exercises to also test on the deeper understanding of the subject matter. In this way I try to optimally prepare the student for his / her test or exam.

However, learning should also be enjoyable. That is why I always strive for a good relationship with the student through a spontaneous and positive approach. I am also very patient. All this lowers the barrier to ask questions and improves the student's learning process.

Are you interested? Do not hesitate to contact me!
See you soon!

Demonstrating a genuine passion for science can be contagious. When children see that their teacher is enthusiastic about the subject, it can ignite their own curiosity and interest in science. Moreover, being able to explain complex scientific concepts in a simple and engaging manner is a crucial skill for a science teacher. Parents want someone who can make science understandable and exciting for their children.

Welcome to my profile.
I am an experienced mathematics and science teacher with over seven years of experience helping students strengthen their understanding, improve their results and become more confident, independent learners.
My lessons are designed for students and families who value high-quality, well-prepared and personalised teaching. Rather than offering a one-size-fits-all course, I adapt each lesson to the student’s level, objectives, school programme and learning style.
I teach students who need to rebuild essential foundations as well as those working on advanced topics, examinations or demanding international programmes such as the European Baccalaureate and International Baccalaureate, as well as, the various Belgian programs.

◆ MY TEACHING APPROACH ◆

• • Initial assessment • •
We begin by identifying the student’s current level, strengths, difficulties and academic objectives.

• • Personalised lesson planning • •
Each student receives a structured learning approach based on their specific needs, curriculum and pace of progress.

• • Clear and accessible explanations • •
Complex concepts are broken down into logical, manageable steps, with visual representations and carefully selected examples.

• • Active problem-solving • •
Students are encouraged to think, explain their reasoning and develop reliable methods for approaching unfamiliar questions.

• • Targeted practice • •
Exercises are selected to address specific weaknesses, consolidate knowledge and prepare effectively for tests and examinations.

• • Regular review and feedback • •
Previously studied material is revisited when necessary, and clear feedback is provided to help the student understand what has improved and what still requires attention.

◆ WHAT YOU CAN EXPECT ◆

Professionalism and reliability are central to my work:
• • Lessons prepared in advance and tailored to the student
• • Punctual and well-structured sessions
• • Patient, respectful and focused teaching
• • Clear explanations without unnecessary complication
• • Constructive and timely feedback
• • Adaptation based on the student’s progress
• • A serious learning environment that remains supportive and encouraging

My objective is not simply to help students complete exercises. I aim to help them understand the underlying concepts, develop stronger reasoning skills and gain the confidence required to work more independently.

Mathematics and science can appear difficult when important foundations are missing or when explanations are poorly adapted to the learner. With the right structure, guidance and practice, these subjects become far more logical, accessible and rewarding.

Q.Why you will love Maths after the lessons?
1.I will help break down concepts to the level of your understanding.
2.I will make sure that I explain all the steps required per topic.
3.At the end of the day, I could've made sure you know and understand the requirements for each question.This will be achieved by exposing you to final examination papers.
4.I make sure I teach all the topics based on the syllabus.
5.I also share useful study tips to make you excel academically.

NOTE; I am a straight forward Tutor who strives to bring out the best in every student on time.I am always innovative by using interactive mode of Teaching Methodology.

I use well structured notes and past papers.Once I teach my student/s a topic, I make sure the lesson is concluded by attempting Examination Questions together.
In addition, each lesson takes 1 hour (60 minutes) duration.That time , is fair enough to have had all the lesson objectives met.


Booking me for a class guarantees excellent grades.
I look forward to be your Tutor.Don't forget to share your review after the lesson/s.I thank you.
