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

From 20.59 £ /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.

If you're looking for an organised and professional teacher to help you achieve your academic goals, look no further! The IB science subjects can be extremely difficult to go through on your own, and I'll be glad to use my experience to help you out.

A couple of things I like to do:

- Initial test or interview to assess your level.
- Use Notion as a platform to share all my resources.
- Use mock papers that lay out the exercises JUST like in the real exams, so you will feel really prepared.
- I give homework when appropriate.
- I provide any kind of mentoring and college counseling. People who study Biology and Chemistry usually want to pursue a clinical career-- and that is a complex process!
