This youtube video I made in the beginning of the year, and it was my first time making one. I could use this in the future in many ways. Maybe one day I would have to make another youtube video explaining my presentation, and now it won't be difficult for me, because I have already made one. My video can also be very helpful for other students who don't understand Elasticity & Utility, Supply & Demand. Even I learned what does words mean now.
