After two years in the MPSI then PSI* preparatory class, I am now a student at the Centrale Lille engineering school. Basically, I've been doing a lot more math and physics than I've slept in the past few years.
I have been teaching at all levels for a little over 3 years! But this is the first time I've tried this platform, can't wait to meet you!
In order for the course to be as constructive as possible, I will base myself on your expectations, the chapters that cause you problems, by reworking the basics so as to navigate thereafter between the different themes of the program. My classes are aimed at all students from college to terminale but also to first and second year students in physics and maths.

Hi, reader! :)

I am probably one of the most enthusiastic and versatile tutors in Amsterdam!

I have been tutoring students for over 10 years at various levels, with a focus on middle and high school students. Many of my students have been preparing for exams such as IB, AP, A-level, and IGCSE.

I hold several relevant degrees, including a PhD and MSc in Financial Justice from the University of Amsterdam, as well as a BS and MS in Engineering from the University of Pennsylvania (an Ivy League institution).

While my main area of expertise is math (ranging from simple arithmetic to advanced university-level calculus), I have also assisted students in preparing for high school level Chemistry and Economics exams.

What sets me apart as a UNIQUE tutor, in addition to my extensive background, is my PERSONAL approach to tutoring. I customize my teaching methods to suit each individual student. This includes the way I present material, work through problems, structure our sessions, and provide tailored feedback to help the student thrive. Additionally, I provide all of my students with my personal phone number, allowing them to contact me OUTSIDE OF SCHEDULED HOURS at NO ADDITIONAL COST if they are struggling while studying on the nights leading up to exams!

For me, tutoring is not just about covering the material; it is about tailoring the learning experience so that students can develop the necessary tools to excel in their courses and eventually become self-sufficient, no longer needing a tutor. :)

Everyone who learns has certain ways of learning that are pleasant and others that are unpleasant.
This is sometimes also due to a certain bias with regard to the subject, sometimes with regard to the way of learning that is normally requested.
In these tutorials I help you make your learning more effective, by making better use of your strengths, compensating for your weak elements, and understanding blockades or attachments, that works better.
The homework guidance is based on concrete lessons that you have to do for school or university and where you can use help. I help with that, especially by asking questions. As a result, you learn more how much you can actually understand yourself, often also from an unusual point of view, which gives energy. And by understanding what you know about one subject, to recognize it in another way in another subject.
In five lessons you will be different in your learning. Initially, we usually work with a course in which you can use help. But after that you know your way better in different subjects, and you learn better and more effectively.

I graduated as a molecular biologist 20 years ago. Since then I have been making films in which I simplify complex biological concepts. I'm a big fan of biology and I think it would be fun to help you get a better grip on the matter. I can help you briefly with specific topics, or help you for a longer period of time to help you succeed, for example.

Molecular biology opens up a fascinating world of invisible processes that sustain all life on Earth. In this introductory class, we will explore the basic molecules that compose living organisms – cells, DNA, RNA, and proteins.

We will first examine cells, the fundamental units of life. Peer inside them with microscopes to understand their structure and function. Next, we will study DNA, the molecule that operates as an instruction manual containing all the information required to build an organism. We will learn how DNA replicates itself and gets passed to new cells during cell division.

From there, we will look at RNA, which translates genetic information from DNA and assists in assembling proteins. Proteins, in turn, carry out most of the work within cells and comprise much of your tissues and organs. We will see how changes in DNA can alter proteins and affect an organism’s traits.

This class will provide an overview of key concepts in molecular biology. You will get to explore the microscopic world that makes life possible! See how cells work and how DNA, RNA, and proteins interact in creative ways to produce the amazing diversity of living things – from simple bacteria to complex humans. It will be an illuminating journey!

Techniques such as mnemonic devices, visual aids, and real-life examples are integral to my method, ensuring that formulas and concepts are not just memorized, but truly understood.

Regular assessments are conducted to track student progress and identify areas needing improvement. These tests also prepare students for their school exams, ultimately boosting their confidence. I understand the importance of keeping parents informed and involved in their child’s academic journey. That's why I provide weekly reports detailing their child’s progress, strengths, and areas for improvement. This continuous feedback loop ensures that parents are aware of their child’s development and can support their learning at home.

Encouraging words and positive feedback are integral to my teaching method. I strive to build students' self-confidence and to instill a love for learning through positive reinforcement. Setting achievable goals for each student, I celebrate their successes and motivate them to strive for excellence. This goal-setting approach not only drives academic success but also fosters a sense of accomplishment and self-worth.

As a tutor, my satisfaction comes from seeing my students excel and reach their full potential. My ultimate goal is to empower students with the knowledge and skills they need to succeed in Science and Maths. I am always available to support my students, offering additional help and resources as needed to ensure their success.

I foster an open environment where students feel comfortable asking questions, no matter how simple they may seem. This curiosity drives deeper understanding and encourages a proactive approach to learning. By incorporating games, puzzles, and interesting activities, I ensure that learning remains fun and engaging, keeping students excited about the subjects.

Join my Foundation Course in Science and Maths and watch your child develop a strong foundation, confidence, and a genuine love for these essential subjects. Let’s work together to achieve academic excellence and make learning a fun and rewarding experience. “Excel in Subjects, Soar in Confidence!”

Lesson Plan: Enthalpy Changes in Chemical Reactions
Grade/Level: Secondary / IGCSE / AS level
Duration: 60 minutes
Topic: Enthalpy Changes in Reactions
Lesson Objectives
By the end of the lesson, students should be able to:
1. Understand that chemical reactions are accompanied by enthalpy changes, which can be exothermic or endothermic.
2. Construct and interpret reaction pathway diagrams, showing enthalpy change and activation energy.
3. Define and use key terms: standard conditions (⦵), enthalpy change of reaction (ΔHr⦵), formation (ΔHf⦵), combustion (ΔHc⦵), and neutralisation (ΔHneut⦵).
Lesson Breakdown (60 minutes)
1. Introduction (5 minutes)
Begin with a real-life hook:
Ask: “Why does burning wood release heat, but dissolving ammonium nitrate in water feels cold?”
Link to lesson: These are examples of exothermic and endothermic reactions.
2. Theory: Enthalpy Changes (10 minutes)
Define enthalpy (H): The heat content of a system at constant pressure.
Define enthalpy change (ΔH): Heat energy transferred during a reaction at constant pressure.
Distinguish:
Exothermic reaction: ΔH is negative (heat released).
Endothermic reaction: ΔH is positive (heat absorbed).
Give simple examples:
Exothermic → combustion of methane.
Endothermic → thermal decomposition of calcium carbonate.
3. Reaction Pathway Diagrams (15 minutes)
Draw and explain two diagrams:
Exothermic pathway: Products lower in energy than reactants, ΔH negative.
Endothermic pathway: Products higher in energy than reactants, ΔH positive.
Introduce activation energy (Ea):Minimum energy needed for reaction to occur.
Label diagrams clearly:
Reactants → peak (activation energy) → products.
Highlight ΔH and Ea.
4. Standard Conditions and Key Enthalpy Terms (15 minutes)
Explain standard conditions (⦵):

298 K (25°C), 101 kPa pressure, substances in standard states.
Define and discuss:
Standard enthalpy change of reaction (ΔHr⦵): Heat change when reaction occurs in molar quantities under standard conditions.
Standard enthalpy of formation (ΔHf⦵): Heat change when 1 mole of compound is formed from its elements in their standard states.
Standard enthalpy of combustion (ΔHc⦵):Heat change when 1 mole of substance is completely burnt in oxygen under standard conditions.
Standard enthalpy of neutralisation (ΔHneut⦵): Heat change when an acid and alkali react to form 1 mole of water under standard conditions.
Use simple examples for each (e.g., combustion of methane, formation of H2O, neutralisation of HCl with NaOH).

5. Guided Practice / Mini Activity (10 minutes)
Students sketch their own reaction pathway diagrams (exothermic and endothermic).
Label ΔH and Ea.
Pair discussion: “Why do we still need activation energy even for exothermic reactions?”

6. Exercise (Homework / Classwork) (5 minutes)
Answer the following questions:
1. State whether each reaction is exothermic or endothermic:
a) Burning propane gas in oxygen.
b) Photosynthesis in plants.
c) Dissolving anhydrous copper(II) sulfate in water.

2. On a reaction pathway diagram:

Show ΔH and Ea for an endothermic reaction.

3. Define the following terms and give one example each:
a) Standard enthalpy of formation (ΔHf⦵)
b) Standard enthalpy of combustion (ΔHc⦵)
c) Standard enthalpy of neutralisation (ΔHneut⦵)

4. Under standard conditions, the enthalpy of combustion of methane is –890 kJ mol−1.

I hope to see you soon and help you out.
I'm 21 years old and currently studying Biomedical Sciences, so I know a bit of what I'm doing :]
