About me

Hello, my name is Nestar Ospina, and I am here to help you with your Physics, Mathematics and Statistics subjects. I am a graduate of the National University of Colombia in Physics, and I have more than 6 years of experience teaching private classes for the Baccalaureate level and first courses of the University. Studying Physics was a discovery for me, since I only knew about Physics and Mathematics what they taught at school, but little by little I realized that the world I was discovering was much broader and more interesting than memorizing some math formulas. At University I learned that Physics focuses on the study of large objects, such as planets or galaxies, down to the smallest ones, such as atoms and molecules. We can study everything from the movement of these planets to the behavior of atoms, thanks to quantum mechanics. Did you know that, on a small scale, atoms behave like waves and not just like small particles of matter? If the system is larger, we can even study the relativity of motion, the mechanics of water, waves! In short, I developed a completely different look at the world I lived in, and I want to share that way of seeing the world with you. If you feel that you are falling behind in a subject, that you do not understand key concepts, or that you are having difficulty solving problems quickly, do not hesitate to contact me for help. With my classes you will train to be able to defend yourself from any question to pass school or enter the University. In the Classgap platform I have tools such as the digital whiteboard to solve problems graphically, documents to take notes, excel to do calculations and more. What are you waiting for to book your first class! I'll wait for you in the virtual classroom!

Resolvió mis dudas!

En total hemos realizado dos ejercicios durante la sesión. En el primer ejercicio me lo explico de manera que no lo entendia y luego con la respuesta que me ofrecio no era correcto del todo y sin acabar de responder todo los apartados. En el segundo, se equivoco parcialmente. En fin, no volveré a probar y dudo de su profesionalidad.

Profesor amable y conoce del tema.

Excelente, comprometido

Excelente su clase

Hoy fue mi primera clase con Nestar y la desfruté mucho. Muchas gracias!

Genial !! voy como avión jajajaj

Clear instructions, and very well explained. I like Nestar for tutoring me solid state physics.
