Have you ever had any private lessons?

I've had private lessons for programming at a school club. That's when my school was chosen as a software-focused university. No matter the major, all students had to take a basic programming class. I decided to help my club members. While I prepared lectures, I realized that just knowing something and teaching it to others is totally different. I could improve my skills and understanding by explaining to all of them. I also felt rewarded when it really worked and finally they made a good result in class.
