Edsembly :: Physics

About your teacher

Hi there! My name is Ivan and I am the founder of Edsembly. I'm passionate about physics, mathematics and programming and built Edsembly as a learning platform to share my knowledge and experiences. I've been teaching as a private tutor in A level and O level physics for 3 years and the students I have taught have shown significant improvements in their results. If you have any questions do not hesitate to reach out to me.
