Chemistry (IB/A-level/AP & first-year uni) — clear, step-by-step lessons with a Chemistry BSc tutor

From 38 C$ /h

Chemistry can be challenging if it’s taught as pure memorization — my goal is to change that. With over 5 years of tutoring experience and a BSc in Chemistry from TU/e, I help students understand the “why” and “how” behind chemistry, turning tricky concepts into something logical and even enjoyable.

This class is for high school students (IB SL/HL, A-level, AP) and first-year university students taking General Chemistry. Lessons are in English and are ideal for international students or anyone who prefers studying in English.

We cover all major topics, including stoichiometry and moles, thermodynamics, equilibrium, acids, bases and buffers, kinetics, electrochemistry, atomic structure, bonding, and organic chemistry basics (nomenclature, mechanisms, isomerism).

A typical 60-minute lesson includes: 1) quick check-in and goal-setting, 2) a clear explanation with one core example, 3) guided practice with feedback, 4) an exam-style problem under light time pressure, and 5) recap and micro-homework with an error log to track recurring mistakes.

Lessons are available online (interactive whiteboard, past papers, custom notes) or in-person in Eindhoven.

About Me

I’m Valerian, a Chemistry BSc from TU/e. I help high-school and first-year university students master Chemistry, Calculus/Math, and high-school Physics.

My tutoring is clear and structured: I diagnose where understanding breaks down, rebuild concepts step by step, and coach problem-solving so students become confident and independent. I care about efficiency, calm progress, and real understanding—not rote memorization. Lessons are in English, online worldwide. If you want clarity and steady results, I’d be happy to help.

Outside of teaching I love dancing, debating, and cooking — things that keep me curious, communicative, and creative, qualities I bring to every lesson.

Calculus & Math (HS + first-year uni) — limits, derivatives, integrals, and problem-solving strategies

38 C$ /h

Math becomes manageable when you see it step by step. I help students build solid foundations and tackle problems with confidence.

For: high-school (algebra, pre-calculus, IB HL math, A-level math) and first-year university Calculus I–II.

We cover functions and graphs, limits and continuity, derivatives and applications (rates, optimization, curve sketching), integrals and applications (area, volume, accumulation), sequences/series, and basic vectors/linear algebra if required.

A typical 60-minute lesson: 1) short diagnostic to spot weak points, 2) concise concept explanation, 3) guided examples → independent practice, 4) exam-style problem under light time pressure, 5) recap and small next-step plan with an error log to track progress.

Available online (interactive whiteboard, problem banks) .

High-School Physics — mechanics, energy, electricity, waves (IB SL / AP 1 / A-level foundations)

31 C$ /h

Physics gets easier when formulas connect to intuition. I guide students step by step so concepts make sense and problems feel solvable.

For: high-school physics (IB SL, AP Physics 1, A-level foundations) and students preparing for exams or needing a stronger base for university.

We cover kinematics, Newton’s laws, forces and friction, energy and power, momentum and collisions, circular motion, simple harmonic motion and waves, basic electricity and DC circuits.

Lesson structure (60 min): 1) goal-setting and concept overview, 2) worked example, 3) guided practice, 4) short timed problem, 5) recap and next-step plan. Mistakes are logged and revisited to ensure steady improvement.

The math, physics, chemistry, and SVT courses of the French or Swiss program of maturity or university are done by either in-depth explanations or by a quick course and summary of essential needs according to the case of each student supported by exercises from the book or evaluations and exams from other high schools.
A special follow-up program to better prepare for the Terminales session.
So that I can give support courses for the 1st year of university in Mathematics - Analysis - Matrices - Statistics - Algebra - Geometry - Physics - Mechanics - Electricity - Chemistry - Organic Chemistry - Biology, Geology.
My experience is too long and for years I have learned methods for each case and for each student to fill in their gaps with the best results of Excellent, Very Good, and Good as mentioned by my students.
I can also help students to better prepare for courses and support them to better prepare for the duties of CNED in science subjects.
Guaranteed response within minutes up to 10 hours maximum.

I am Mavi, a physics engineer working at an aerospace company.
I have been teaching private lessons at the primary, secondary, high school, and university preparatory levels for 11 years. I teach mathematics, physics, chemistry, and science. I have a good command of the curricula of IB, IGCSE, American, Hong Kong, and international schools.

Additionally, I hold the position of president at the Astronomy Society, where I foster my students' interest in astronomy and science beyond the lessons. I prepare the learning environment by incorporating experiments and exploration, moving away from rote education. I often bring experimental materials to class, aiming to make learning memorable through hands-on experiments.

As an educational mentor, I approach my students as if they were my siblings, valuing creativity. I have a deep passion for mathematics, physics, and science. I am dedicated to helping students understand and learn because life encompasses both SCIENCE and ART. The more people I can inspire to know, understand, and love mathematics, physics, and chemistry, the more proud I am.

Are you curious about how nature works?

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.
