Using common sense to understand Mathematics and Physics, to get the idea

For a short period of time, my daughter started to feel comfortable in her mathematics class. She was able to understand what her teacher was talking in class and even started actively participating.
All this happened after a set of private sessions with her tutor.
The most important thing was that he taught her how to study by herself and be active in class.
After the tutorial sessions, she even started to help her classmates understand different topics.
Thank you, Professor!
