Nothing beats one-on-one lessons.
I am a qualified, experienced, and certified international tutor with a strong familiarity with the Cambridge IGCSE/A-Levels/O-Levels & IB Diploma curricula. I offer both ONLINE and IN-PERSON lessons in PHYSICS, CHEMISTRY, and BIOLOGY, following the British, American, and Indian curricula.
My classes are available at affordable rates and can be conducted in-person or online. I adopt a student-oriented teaching style, striving to provide the best private lessons for my students.

With 6 years of professional experience in science (Physics, Chemistry, and biology), I am well-versed in both the British and American curricula and I possess a high level of competency. I have taught students from various countries, including Belgium, Spain, Switzerland, Japan, the USA, the Caribbean, the UK, India, China, Singapore, Malaysia, Turkey, the Netherlands, Luxembourg, Germany, France, Italy, and South Africa.

Book a lesson with me, and we can start on any day and time that suits you.

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!

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.
