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

From 186.65 CNY /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

186.65 CNY /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)

154.19 CNY /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.

In my class, I would like to help my students with the necessary tutoring and proper direction towards understanding natural science subjects such as Physics, Chemistry, and Mathematics for students at IB level, high school level, and school level. I am familiar with the European School system, International School System, and A-level.

I myself was among the top 3s during my high school days and since then I have a great experience tutoring. I would look into problems from the student's point of view. This enables me to know where they are having difficulty and then help them study nicely.

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.

Welcome to university students or masters and doctoral students!!! I teach the course of Natural Products Chemistry or Phytochemistry or Pharmacognosy. In this class we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy, spectroscopy, mass spectrometry, magnetic resonance and advanced analysis devices used in this field.

This is in addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical and laboratory methods that are carried out in the laboratory to conduct toxicity, antioxidant, and diabetes analyses, etc.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for science and chemistry curricula.

With my qualifications and experience, I hold a master’s degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other graduate degrees and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mendus Organization of the European Union.
